Theoretically how many grams of malachite should be formed when 1.5 moles of Copper Sulphate reacts with an excess of sodium carbonate?

Answer 1

CuSO4 + Na2CO3 ==> CuCO3 + Na2SO4

mols CuSO4 = 1.5
mols CuCO3 = 1.5 x (1 mol CuCO3/1 mol CuSO4) = 1.5
grams CuCO3 = mols CuCO3 x molar mass CuCO3.

Answer 2

165.837
