Answer:
The percentage composition of CA(OH)2 is as follows;
54.05% Ca.
43.24% O
2.70% H
The percentage composition of Ca(OH)2 can be obtained by first determining the molar mass of Ca(OH)2 as follows;
Ca = 40
O = 16
H = 1
In essence, the molar mass of Ca(OH)2 is;
Ca(OH)2 = 40 + (16+1) × 2
Ca(OH)2 = 74
Therefore;
% Ca = 40/74 × 100% = 54.05%
% O = 32/74 × 100% = 43.24%
% Ca = 2/74 × 100% = 2.70%
