WebMay 31, 2014 · The proper name for CuSO4 is copper (II) sulphate - the Roman numerals denote the oxidation state for any atom which has variable oxidation states, such as transition metals. There are several ways to work this out. We could start from a knowledge that the sulphate ion has a 2- charge, so the copper ion must have a 2+ charge and … Webf) If 24.0 g of CuSO 4 and 24.0 g of KCN react, what is the theoretical yield of C2 N2 (in g)? 24.0 g CuSO4 × 1 mol CuSO4/159.61 g CuSO4 = 0.1504 mol CuSO4 24.0 g KCN × 1 mol KCN/65.12 g KCN = 0.3684 mol KCN Since CuSO4 is limiting, we use its number of moles to calculate the theoretical yield of C2N2: 0.1504 mol CuSO4 × 0.5 mol C2N2/mol ...
