Calculate the mass of 0.1 mole of the following: CaCO3 (Ca = 40, Na = 23, Mg = 24, S = 32, C = 12, Cl = 35.5, O = 16, H = 1)

Calculate the mass of 0.1 mole of the following:

CaCO₃

(Ca = 40, Na = 23, Mg = 24, S = 32, C = 12, Cl = 35.5, O = 16, H = 1)

संख्यात्मक

Molar weight = [40 + 12 + (3 x 16)] = 100 g

∴ 0.1 mole of CaCO₃ has mass =100 (molar mass) x 0.1

= 10 g
