Answer to Question #162377 in Chemistry for Ava Brooke

Question

Using the following chemical equation how many grams of calcium chloride can be produced by reacting 57.09 g of calcium hydroxide?

2HCl + Ca(OH)₂ -> 2H₂O + CaCl₂

Answer 1

2HCl + Ca(OH)₂ -> 2H₂O + CaCl₂

According to the equation, the mass of calcium chloride equals:

m(CaCl2) = m(Ca(OH)₂) × Mr(CaCl₂) / Mr(Ca(OH)₂) = 57.09 g × 110.98 g/mol / 74.09 g/mol = 85.52 g

Answer: 85.52 g
