How many atoms of zinc are there in 135 gms?

Answer 1

135 grams zinc (1 mole Zn/65.41 grams)(6.022 X 10^23/1mole Zn)

= 1.24 X 10^24 atoms of zinc

Answer 2

To calculate the number of atoms, we need to use Avogadro's number and the molecular weight of zinc. The molar mass of zinc is 65.38 g/mol. First, convert grams to moles: 135 g / 65.38 g/mol = 2.06 moles. Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms: 2.06 moles * 6.022 x 10^23 atoms/mol = 1.24 x 10^24 atoms of zinc.
