White vitriol is the compound known as zinc sulphate
Which has the formula ZnSO₄
mass percent = (mass of element in 1 mole of compound / mass of 1 mole of compound) x 100
mass of Zn = 65.4
mass of S = 32
mass of O = 16
There mass of 1 mole of ZnSO₄
= 65.4 + 32 + (16×4)
= 161.4
% mass of zinc = 65.4/161.4 × 100%
= 40.5%
The most commonly encountered form of this compound is zinc sulphate heptahydrate
Formula: ZnSO₄.7H₂O
mass of 1 mole of it is 161.4 + (18x7) = 287.4
% mass of zinc in the heptahydrate = 65.4/287.4 × 100%
= 22.76%
