Given that the chemical formula for calcium hydroxide= (Ca(OH)2)
Using the above formula, we calculate the formula mass of this compound.
For calcium hydroxide, the formula mass can be calculated as,
Formulamass=onecalcium
1CA (a/mu = 40) = 40
20 (a/mu = 16) =2×16=32
2H (a/mu = 1) = 2 x 1= 2
%Ca= 40/ 72 ×100
%Ca= 54%
