(a) Interpretation: The total number of atoms in the given species needs to be calculated. Concept introduction: According to Avogadro’s law , in 1 mol of a substance there are 6.023 × 10 23 atoms. Thus, from number of moles and Avogadro’s number , the number of atoms of an element can be calculated as follows: N = n × N A Here, n is number of moles and N A is Avogadro’s number with a constant value of 6.023 × 10 23 .
