CaO+H

O→Ca(OH)

One mole of CaO will give one mole of calcium hydroxide.

The molar mass of calcium hydroxide is 40.1+2(16+1)=74.1g/mol.

370 grams of calcium hydroxide corresponds to

74.1g/mol

370g

=5.0 moles.

Hence, 5.0 moles of CaO are required to react with an excess of water to form 370 grams of calcium hydroxide.
