| Determine the mass of salt and the amount of water obtained by the interaction of copper hydroxide (2+) with 58.5 g of sulfuric acid.
Given:
m (H2SO4) = 58.5 g
To find:
m (salt) -?
n (H2O) -?
1) Cu (OH) 2 + H2SO4 => CuSO4 + 2H2O;
2) n (H2SO4) = m / M = 58.5 / 98 = 0.6 mol;
3) n (CuSO4) = n (H2SO4) = 0.6 mol;
4) m (CuSO4) = n * M = 0.6 * 160 = 96 g;
5) n (H2O) = n (H2SO4) * 2 = 0.6 * 2 = 1.2 mol.
Answer: The mass of CuSO4 is 96 g; the amount of H2O substance is 1.2 mol.
