Another possible source of confusion is that some older textbooks use the term " molecular weight " to mean the molar mass.

Many chemists use molecular mass as a synonym of molar mass, differing only in units ( see average molecular mass below ).

The actual numerical difference can be very small when considering small molecules and the molecular mass of the most common isotopomer in which case the error only matters to physicists and a small subset of highly specialized chemists ; however it is always more correct, accurate and consistent to use molar mass in any bulk stoichiometric calculations.

Other methods include the use of the molar volume or the measurement of electric charge.

When the molar mass is greater than 1000 g / mol, it is rarely appropriate to use more than one decimal place.

Chemical equations make use of the standard molar entropy of reactants and products to find the standard entropy of reaction:

* Various vestigial body parts, like the femur and pelvis in whales ( evolution says the ancestor of whales lived on land ) or the third molar-or ' wisdom teeth ' - in humans ( whereas some other primates with differing jaw shapes make use of the third molar ).

These molar fractions will become of use when applying Equation 1 below.

The use of equivalent weights in general chemistry has largely been superseded by the use of molar masses.

In addition, the pilots of the Avro Vulcan or Handley Page Victor bombers could tie their systems into those of the missile and make use of the guidance system to help plot their own flight plan, since the unit in the missile was more advanced than that in the aircraft.

Not all calendars use the solar year as a unit.

In most fields its use has been replaced by the SI unit of energy, the joule.

However, it remains a commonly used unit for energies in the field of chemistry, and in many countries it remains in common use as a unit of food energy.

The use of money as a medium of exchange and unit of account is necessary to solve the first two problems of economic calculation.

Some writers have argued that with detailed use of real unit accounting and demand surveys a planned economy could operate without a capital market, in a situation of abundance, The purpose of the price mechanism is to allow individuals to recognise the opportunity cost of decisions: in a state of abundance, there is no such cost.

Nuclear power plants can produce a huge amount of power from a single unit, but since most of the power plants built before 1990 use hard water as a coolant, setting them up near a source of hard water is the only viable economic option.

In certain fields, such as plasma physics, it is convenient to use the electronvolt as a unit of temperature.

Early evidence of their use in Britain includes: an equal hour horary quadrant from 1396, in England, a 1445 inscription on the tower of Heathfield Church, Sussex ; a 1448 inscription on a wooden lych-gate of Bray Church, Berkshire ; and a 1487 inscription on the belfry door at Piddletrenthide church, Dorset ; and in Scotland a 1470 inscription on the tomb of the first Earl of Huntly in Elgin Cathedral.

This helps explain why 80 % of mined diamonds ( equal to about 100 million carats or 20 tonnes annually ), unsuitable for use as gemstones and known as bort, are destined for industrial use.

Additionally, many Esperantists use the language as a window to the larger world, to meet people from other countries on an equal footing, and for travel.

After a very heated national debate, legislation was passed in 1985 that gave women an equal right to decide what surname or surnames they and their children would use.

The Rankine temperature scale was created to use degree intervals the same size as those of the Fahrenheit scale, such that a temperature difference of one degree Rankine ( 1 R ) is equal to a difference of 1 ° F, except that absolute zero is 0 R – the same way that the Kelvin temperature scale matches the Celsius scale, except that absolute zero is 0 K. The Fahrenheit scale uses ( in the same manner as the later Celsius scale ) the symbol ° to denote a point on the temperature scale and the letter F to indicate the use of the Fahrenheit scale ( e. g. " Gallium melts at 85. 5763 ° F "), as well as to denote a difference between temperatures or an uncertainty in temperature ( e. g. " The output of the heat exchanger experiences an increase of 72 ° F " and " Our standard uncertainty is ± 5 ° F ").

This dictum led to a deep study of possible compass and straightedge constructions, and three classic construction problems: how to use these tools to trisect an angle, to construct a cube twice the volume of a given cube, and to construct a square equal in area to a given circle.

His work is notable for the use of the zeta function ζ ( s ) ( for real values of the argument " s ", as are works of Leonhard Euler, as early as 1737 ) predating Riemann's celebrated memoir of 1859, and he succeeded in proving a slightly weaker form of the asymptotic law, namely, that if the limit of π ( x )/( x / ln ( x )) as x goes to infinity exists at all, then it is necessarily equal to one.

Despite the political campaigns launched in order to put Sardinian on an equal footing with Italian, and any emotive value linked to Sardinian identity, the sociolinguistic situation in Sardinia due to several reasons, mainly political and socioeconomic ( the gradual depopulation of the island's interior and rural exodus towards more urbanized and industrialized areas, the forced use of Italian presented as a prerequisite to get jobs and as one of the keys to social advancement, the barriers to communication between the dialectal varieties etc.

As Tanzanians pride themselves on living together with their diversity, the use of a statistic that is conveniently equal is seen as avoiding rivalries between the various religious groups by not identifying the majority.
