WebMay 16, 2009 · 93,341,000,000,000,000,000,000,000 or 933.41 x 1023 atoms of arsenic. You just take Avogadro's number (6.022 x 1023) and multiply 6.022 by the number of moles (155) and then multiply the product ... Number of Atoms = (Given Mass/Molar Mass) * Avogadro’s Number. Number of Atoms = (78/40.078) * 6.02 * 10^ {23} Number of Atoms = 1.9462 * 6.02 * 10^ {23} Number of Atoms = 1.171 * 10^ {+24} For further verification, you can let this grams to atoms calculator do that for you in seconds. See more Whether you are going to convert grams to atoms or vice versa, you must have a sound knowledge of the Avogadro’s Number.
