Answer:

111.6 grams

Explanation:

We will apply the concept of mole ratio to solve this question.

The mole ratio of H2O to Ca(OH)2 in the reaction above is 1 : 1.

This means that the moles of H2O that reacts to form Ca(OH)2 are 6.2 moles.

Molar mass of water = 16 + 2 = 18 grams per mole

Moles = mass/molar mass

6.2 moles = mass/18

Mass = 18 × 6.2 = 111.6 grams
