Question

calculate the no of ca in 10g caco3 in mole

Answer 1

Answer:

.1 moles

Explanation:

Moles in 10g of CaCO_3 = 10/100 = 0.1 mol

Atoms in 1 mol of CaCO_3 = 6.022xx10^23

Atoms in 0.1 mol CaCO_3 = 0.1xx6.022xx10^23 = 6.022xx10^22

We have similar amount of Ca and C atoms.

Amount of Ca moles in 10g of CaCO_3 = 0.1

Mass of carbon in 0.1mol of CaCO_3 = 40xx0.1 = 4g
