Step 1: Make sure the reaction equation is balanced.
Step 2: Calculate initial moles of H3PO4.
H2 is produced by the reaction of 118.5 mL of a 0.8775-M solution of H3PO4 according to the following equation: 2Cr + 2H3PO4 ⟶ 3H2 + 2CrPO4.
(a) Outline the steps necessary to determine the number of moles and mass of H2.
