Question

Calculate the mass percent of each element present in the molecule of calcium carbonate.
(ca =40u, C = 12M, 0 = 16u)​

Answer 1

Answer:CaCO₃

Molecular mass = 100 g

Mass% of element = (Mass of element / Mass of molecule) × 100

Mass percentage of

Calcium = [(40 g) / (100 g)] × 100 = 40%

Carbon = [(12 g) / (100 g)] × 100 = 12%

Oxygen = [(16 × 3 g) / (100 g)] × 100 = 48%
