Question

calculate the mass of 1.5 gram atom of calcium(atomic mass=40

Answer 1

hi there


If atomic mass = 40
molecular mass = 1. 5x40=60


thank you

Answer 2

Answer : The mass of 1.5 gram atom of calcium is 60 gram.

Solution : Given,

Mass of Ca = 1.5 gram atom

Molar mass of Ca = 40 g/mole

As we know that, one mole is equal to the one gram atom which is also equal to the molar mass.

1 mole = 1 gram atom = Molar mass

As per question,

1 gram atom of calcium weigh = 40 gram

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

Therefore, the mass of 1.5 gram atom of calcium is 60 gram.
