(a) Interpretation: The element having the smaller molar mass needs to be determined. Concept introduction: The number of moles of an atom of element is related to mass and molar mass as follows: n = m M Here, m is mass of atom of element in grams and M is molar mass in grams/mol. In 1 mol of an element the number of atoms is 6.023 × 10 23 and mass of 1 mol of an element is molar mass thus, mass of 6.023 × 10 23 of element is molar mass.
