A student, using the reaction in 3.(1), combined 1.00 g of K_3 [RhCl_6] with 25.0 mL of 1.25 MK_2C_2O_4, and isolated 0.96 g of K_3[Rh(C_2O_4)_3]. (1) Calculate the number of moles of K_3[RhCl_6] the student used. (2) Calculate the number of moles of K_2C_2O_4 the student used. (3) Determine which reactant is the limiting reagent. Include all appropriate calculations. (4) Calculate the theoretical yield of the synthesis, in grams, of K_3 [Rh(C_2O_4)_3].
