The relative atomic mass ( historically and commonly also called " atomic weight ") of an element is the average of the atomic masses of all the chemical element's isotopes as found in a particular environment, weighted by isotopic abundance, relative to the atomic mass unit ( u ).

* μ < sub > e </ sub > is the average molecular weight per electron, which depends upon the chemical composition of the star.

A meta-analysis of 16 trials of 2 – 12 months ' duration found that low-fat diets ( without intentional restriction of caloric intake ) resulted in average weight loss of 3. 2 kg ( 7. 1 lb ) over habitual eating.

A worldwide average of the chemical composition of granite, by weight percent:

With an average atomic weight of ( for hydrogen-1 ), hydrogen is the lightest element and its monatomic form ( H < sub > 1 </ sub >) is the most abundant chemical substance, constituting roughly 75 % of the Universe's baryonic mass.

The weighted harmonic mean is the correct approach to determine the average specific gravity of a mixture when the composition by weight is known.

Here the atomic weight of the lightest element and the heaviest are summed, and averaged, and the average is found to be very close to that of the intermediate weight element.

Currently the entire Earth contains over 75 billion tons ( 150 trillion pounds or about 6. 8 x 10 < sup > 13 </ sup > kilograms ) of biomass ( life ), which lives within various environments within the biosphere .< ref > The figure " about one-half of one percent " takes into account the following ( See, e. g.,, which takes global average weight as 60 kg.

), the total human biomass is the average weight multiplied by the current human population of approximately 6. 5 billion ( see, e. g., ): Assuming 60 – 70 kg to be the average human mass ( approximately 130 – 150 lb on the average ), an approximation of total global human mass of between 390 billion ( 390 × 10 < sup > 9 </ sup >) and 455 billion kg ( between 845 billion and 975 billion lb, or about 423 million – 488 million short tons ).

Common examples are the number average molecular weight and weight average molecular weight.

The U. S. National Toxicology Program suggests that the average American consume at most 12. 5 mg / day of solanine from potatoes ( the toxic dose is actually several times this, depending on body weight ).

Somewhat uneven in interest for an average reader, eight or ten of these are among the finest of their kind in literature.

They tried to outface him, but Joseph Simmons was as wide as two average men, and it would have taken braver men than these were to outface him.

Of these states the average `` change-over '' point ( at which a car is substituted for allowances ) is 13,200 miles per year.

Since most European cars average more miles per gallon of gasoline than American cars, it naturally follows that the cost per kilometer for these models will be less, but the greater seating capacity of the large American cars will equalize this, provided your group is sufficiently large to fill a 7-passenger limousine.

the extreme measurements of these fall between the lower limit of the Brookfield brood and its average.

Though the sales gains these two dealers are experiencing are above average for their business, farm equipment sales are climbing in most rural areas.

The International Bureau of Weights and Measures ( BIPM, France ), combines these measurements to retrospectively calculate the weighted average that forms the most stable time scale possible.

Wind direction is calculated from these cyclical changes in cupwheel speed, while wind speed is as usual determined from the average cupwheel speed.

Many areas average of rain per week, and these can use a cistern as small as.

The average adult has a blood volume of roughly 5 liters ( 1. 3 gal ), composed of plasma and several kinds of cells ( occasionally called corpuscles ); these formed elements of the blood are erythrocytes ( red blood cells, RBCs ), leukocytes ( white blood cells ), and thrombocytes ( platelets ).

On average one of these calves will become a replacement dairy cow, and some of the rest may be reared for beef or veal ; however some are effectively produced solely to allow the cow to produce milk.

On the average, at least twice each decade houses, farms, and harbor facilities are devastated by these great storms.

Even with no external electric field applied, these electrons move about randomly due to thermal energy but, on average, there is zero net current within the metal.

At room temperature, the average speed of these random motions is 10 < sup > 6 </ sup > metres per second.

Though the name came to be commonly used to refer to the whole of southern Mesopotamia, Chaldea proper was in fact the vast plain in the far south east formed by the deposits of the Euphrates and the Tigris, extending to about four hundred miles along the course of these rivers, and about a hundred miles in average width.

The rest of the Bebop crew, with the exception of Ed, often fail to notice these qualities and treat Ein as an average pet.

Property values are depressed, resulting in a smaller tax base for these three provinces, particularly when compared with the national average which benefits from central and western Canadian economic growth.

In physical sciences, numerical values ( such as constants, quantities, or scales of measurement ) are called conventional if they do not represent a measured property of nature, but originate in a convention, for example an average of many measurements, agreed between the scientists working with these values.

Compression algorithms can average a color across these similar areas to reduce space, in a manner similar to those used in JPEG image compression.

The average age of the officers whose names were listed as signing the letter was 74, the oldest was 98, and Servicemembers United noted that " only a small fraction of these officers have even served in the military during the ' Don't Ask, Don't Tell ' period, much less in the 21st century military.

Any convex polyhedron can be distorted into a canonical form, in which a midsphere ( or intersphere ) exists tangent to every edge, such that the average position of these points is the center of the sphere, and this form is unique up to congruences.

On average, 95 % of the participants in these early trials receive no benefit, but all are exposed to the risk of adverse effects.

This yields a useful expression for the average power generation for these devices in the absence of chemical reactions

The period over which the average is calculated is often one hour, but shorter periods ( e. g., 15 minutes ) may be used where it is known that there are short spurts of demand and a traffic measurement is desired that does not mask these spurts.

An alternative is to calculate a busy hour traffic value separately for each day ( which may correspond to slightly different times each day ) and take the average of these values.
