This calculator takes and generates results of many common units. https://www.calculatorsoup.com - Online Calculators. In cases where objects undergo acceleration through other forces (such as a centrifuge), weight is determined by multiplying the object's mass by the total acceleration away from free fall (known as proper acceleration). Their mass, however, would still be 70 kg on the moon. An inflated balloon, for example, would have significantly less mass than a golf ball made of silver. All rights reserved. ; Fred Senese, Jefferson Laboratory: It's Elemental - The Element Boron. Scientists express atomic weights in terms of grams per mole, so the resulting equation looks like this: atomic weight expressed in atomic mass units = grams/mole. Mass is typically defined as the amount of matter within an object. This is a basic mass calculator based on density and volume. B.8 Factors for Units Listed Alphabetically and On earth, this value is approximately 9.8 m/s2. Or, you can find the single factor you need by dividing the A factor by the B factor. In the given example, multiply Avogadro's constant by 5 to discover that the sample contains 3.01 x 10^24 individual boron atoms. In circumstances where the gravitational field is constant, the weight of an object is proportional to its mass, and there is no issue with using the same units to express both. To calculate the number of atoms in a sample, divide its weight in grams by the amu atomic mass from the periodic table, then multiply the result by Avogadro's number: 6.02 x 10^23. 2011. If you have all three pieces of information -- atomic weight, grams and Avogadro's number -- you can calculate the number of atoms in the sample. The words of mass and weight are frequently used interchangeably, but even though mass is often expressed by measuring the weight of an object using a spring scale, they are not equivalent. If your sample of boron weighed 54.05 g, your equation would look like this: mole = 54.05 10.811. While mass is defined by F = ma, in situations where density and volume of the object are known, mass is also commonly calculated using the following equation, as in the calculator provided: In the above equation, m is mass, is density, and V is volume. Wikipedia, The Free Encyclopedia, last visited 24 Jun. Further details are available on the density calculator. Weight, on the other hand, changes based on gravity, as it is a measure of an object's resistance to its natural state of freefall. Negative numbers, small numbers and numbers that do not seem to fit with the sample size mean a mathematical error. In scientific notation, it would appear like this: u = g/mole. Keep an eye on your exponents when you convert your answer into scientific notation; note how the exponent in the example changed from 10^23 to 10^24. In this example, you would have 5 moles of boron. Divide the grams of your sample by its atomic weight to derive the number of moles the sample contains.
