Reaction of zinc hydroxide with sulfuric acid.
Zn (OH) 2 + H2SO4 = ZnSO4 + 2H2O.
The number of moles of starting materials according to the reaction equation will be equal.
n (H2SO4) = n (Zn (OH) 2) = 0.1 mol.
The mass of zinc hydroxide reacted.
m (Zn (OH) 2) = n • Mr = 0.1 mol • 99 g / mol = 9.9 g.
