calculating theoretical yield for this experiment. It is a dehydration synthesis where one mol of hydrated salt yields 3 mol hydrates and 1 mol of anhydrous salt. How do I calculate the theoretical yield if only 0.0031 mol of hydrated salt was used? How do I get the mol of H2O theoretically? The formula is K3Fe(C2O4)3 • 3H2O
