ChemistryIntroductory Chemistry: A Foundation(a) Interpretation: The mass of given sample should be calculated. Concept Introduction: Number of moles is related to mass and molar mass as follows: n = m M Here, m is mass and M is molar mass. According to Avogadro’s law, 1 mole of a substance contains 6.023 × 10 23 atoms. This is known as Avogadro’s number and denoted by symbol N A . Thus, number of molecules can be calculated from number of moles using the following conversion factor: ( 6.023 × 10 23 molecules 1 mol ) .Start your trial now! First week only $4.99!*arrow_forward*
