To find the total mass of the reactants, we need to calculate the total mass of FeCl3 and 3H2O.
FeCl3 has a molecular mass of 56 (Fe) + 3(35) (Cl) = 161 amu
3H2O has a molecular mass of 3(2+16) (H2O) = 54 amu
Total mass of the reactants = 161 amu + 54 amu = 215 amu
Therefore, the total mass of the reactants is 215 amu.
Use the equation and the table to answer the question.
