Answer:

9.92 g of Cl

Step-by-step explanation:

Well first find out the molar mass of calcium hypochlorite.

The molecular formula is,

CaO₂Cl₂

Adding the atomic masses we get the molar mass = 142.98 g/mol

This means,

142.98 f of CaO₂Cl₂ = 70.91 g of Cl

Therefore,

20 g of CaO₂Cl₂ = X

Solving for X,

X = (70.91 g of Cl × 20 g of CaO₂Cl₂) ÷ 142.98 f of CaO₂Cl₂

X = 9.92 g of Cl
