Answer to Question #164185 in Chemistry for Ava Brooke

Question

Using the following chemical equation how many grams of water can be produced by reacting 15.33 g of hydrochloric acid (HCl)?

2HCl + Ca(OH)₂ -> 2H₂O + CaCl₂

Answer 1

According to the equation, equal numbers of moles of HCl and water must react and be produced, respectively. From here:

m(water) = [m(HCl) × 2 × Mr(water)] / [2 × Mr(HCl)] = [15.33 g × 2 × 18 g/mol] / [2 × 36.5] = 7.56 g

Answer: 7.56 g
