To find the total mass of the reactants, we need to add up the masses of each element involved in the reaction.
FeCl3 3H2O:
Fe = 56 amu
Cl = 35 amu x 3 = 105 amu
H = 1 amu x 6 = 6 amu
O = 16 amu x 3 = 48 amu
Total mass of FeCl3 3H2O:
56 + 105 + 6 + 48 = 215 amu
Therefore, the total mass of the reactants is 215 amu.
