How many moles of calcium carbonate (CaCO₃) are present in 10 g of the substance? (Ca = 40 u ; C = 12 u ; O = 16 u)

Academic Chemistry NCERT Class 9

Mass of calcium carbonate = 10g

Molecular mass of calcium carbonate = (1 × 40) + (1 × 12) + (3 × 16) = 100g

Number of moles in 100g of calcium carbonate = 1 mole

Therefore, number of moles in 10g of calcium carbonate is 0.1.
