anggap massa CaO=x gram
mol CaO = x/56 mol
maka massa Na2O=29,8-x gram
mol Na2O= 29,8-x/62
jumlah HCl yang terpakai untuk 10ml=
Molar=mol/vol
4=mol/0,025
mol=0,1mol
untuk 100ml
0,1 x 10= 1mol
(x/28 + 29,8-x/62) = 1
(62x + 834,4 -28x)/1736=1
34x + 834,4 = 1736
34x=901,6
x=26,51764706g ≈ 26,52 g
massa CaO=26,52g
massa Na2O=29,8-26,52=3,28g
