Answer: We are told to find the number of atoms present in 1 g of Zn. Since the molar mass of Zn is equal to 65.38 g/mol, and we know that 1 mole of Zn has a mass equal to 65.38 g, we will calculate the number of atoms as follows: The number of atoms in 1 mole of Zinc is equal to 6.022×1023atoms 6.022 × 10 23 a t o m s .
