Answer to Question #87052 in General Chemistry for Douglas

Question

How many grams of CuCO3(s) would be formed from the copper ions in 47.7 mL of 0.696 M CuSO4?

Answer 1

net ionic equation Cu²⁺_(aq) + CO₃^2-_(aq) = CuCO_3(s)

1.  Number of moles of Cu²⁺_(aq) = CuSO₄ = n =c x V = 0.696 moles/L x 0.0477 L = 0.0332 moles
2. According to reaction stoichiometry number of moles of CuCO₃ = CuSO₄ = 0.0332 moles
3. Mass of CuCO₃ = MW x n = 123.55 g/mol x 0.0332 moles = 4.1 g
