| Determine the mass of salt and the amount of water substance obtained by the reaction of copper (II) hydroxide with 58.8 g of sulfuric acid.
Given:
m (H2SO4) = 58.8 g.
m (salt) -?
m (H2O) -?
Decision:
1) Cu (OH) 2 + H2SO4 = CuSO4 + 2H2O
2) n (H2SO4) = 58.8 / 98 = 0.6 mol
3) n (salts) = n (H2SO4) = 0.6 mol
4) m (CuSO4) = 0.6 * 160 = 96 g.
5) n (H2O) = 0.6 * 2 = 1.2 mol
Answer: 96 g, 1.2 mol
