Question

Quizplus · Accepted Answer

The balanced chemical equation is CaO + H2O → Ca(OH)2. From this equation, we see that 1 mole of CaO reacts with 1 mole of water. The molar mass of water is 18.02 g/mol, so 1 mole of water weighs 18.02 g. Therefore, 1.00 mole of CaO will require 1.00 mole of water, which weighs 18.02 g. Hence, the answer is 18.02 grams (option C).
