3 Ways to Calculate Atomic Mass - wikiHow
WebThe number of atoms in a formula may be calculated using the weight of a sample, its atomic mass from the periodic table and a constant known as Avogadro’s number. Once molar mass is known, the original weight of the sample is divided by the molar mass then multiplied by Avogadro's number. WebSep 9, 2016 · After that, I took percentages of this to calculate the number of moles of each element in the sample of urea (for example, 46.65% of 279.71 to find the number of moles of nitrogen). Finally, I multiplied each of these numbers in moles by Avogadro's number ($6.022\times10^{23}$) to obtain the number of atoms.
