Zinc citrate (Zn_3(C_6H_5O_7)_2) is an ingredient in toothpaste. It is synthesized by the reaction of zinc carbonate with citric acid. 3ZnCO_3(s) + 2C_6H_8O_7(aq) ---> Zn_3(C_6H_8O_7)_2(aq) + 3H_2O(l) + 3CO_2(g). If there are 5.1 mol of ZnCO_3 and 2.05 mol of C_6H_8O_7, which is the reactant in excess? And how much Zn_3(C_6H_5O_7)_2 would be produced under the second condition? Answer in units of mol.
