Question

What mass of zinc contains the same number of atoms as 500.0 g of gold?

Answer 1

Answer:

              166 g of Zinc

Explanation:

First calculate moles of Gold.

Moles = Mass / M.Mass

Moles = 500 g / 196.96 g/mol

Moles = 2.54 mol

Secondly, calculate mass of Zinc using moles of Gold.

Mass = Moles × M.Mass

Mass = 2.54 mol × 65.36 g/mol

Mass = 166 g of Zinc
