Answer 2

The mass of 1.5 g atom of calcium is 60 gram.

Solution- Given that,

Mass of Ca = 1.5 g atom

Molar mass of Ca = 40 g/mole

1 mole = 1 gram atom -molar mass.

1 gram atom of calcium weigh = 40 g

35.125 gram of calcium weigh = 1.5 × 40 = 60 g

Hence, the mass of 1.5 g atom of calcium is 60 g
