CaO has a gram molecular mass of 40.08 + 16.00 = 56.08. The reaction between CaO and water to produce calcium hydroxide, Ca(OH)2, occurs according to the equation
CaO + H2O = Ca(OH)2. Therefore, the same number of moles of calcium hydroxide can be produced as the moles of CaO supplied. The gram molecular mass of Ca(OH)2 is 40.08 + 2 (16.00 + 1.008) = 74.10. Therefore, the mass of calcium hydroxide produced with have the same ratio to the mass of calcium oxide supplied as 74.10 has to 56.08, or 412 grams, to the justified number of significant digits.
