I'm confused on how to solves these questions.

1. You will need to prepare 40. mL of 1.0M oxalic acid solution (solid oxalic acid is H2C2O42H2O ) and 10. mL of 2.0M potassium oxalate solution (solid potassium oxalate is K2C2O4.H2O ). Show a summary of your calculations. Have the instructor check your answers before you begin preparing the solutions. mass of oxalic acid needed mass of potassium oxalate needed A. Preparation of the Complex Mass of ferrous ammonium sulfate hexahydrate used (This is the limiting reactant) Total mass of dry final (green) product 1.
