The reaction mixture initially contains 2.5 grams of ferrous ammonium sulfate hexahydrate and 10.00 mL of 1.5 M oxalic acid. Determine the limiting reactant.

Answer 1

convert to moles
the reaction equation will then indicate the ratios used, and thus which will be exhausted.

Answer 2

Post your work if you get stuck. The molar mass of ferrous ammonium sulfate hexahydrate is 392.1.
