Calculate the mass (g) of a 10% calcium hydroxide solution required to react with 67.2 liters

Calculate the mass (g) of a 10% calcium hydroxide solution required to react with 67.2 liters of carbon dioxide. How many grams of sediment is formed?

Solution:
1) Ca (OH) ₂ + CO₂ = CaCO₃ + H₂O

2) n (CO₂) = 67.2 / 22.4 = 3 mol

3) n (СО₂) = n (СаСО₃) = nСа (ОН) ₂) = 3 mol

4) m (Ca (OH) ₂) = 3 * 74 = 222 g

m (solution) = 222 * 100/10 = 2220 g
m (CaCO₃) = 100 * 3 = 300 g
Answer: 2220 g, 300 g.
