explain which one is correct
To find the total mass of the reactants, we need to add up the atomic masses of all the elements involved in the reaction.
FeCl3: Fe = 56 amu, Cl = 35.5 amu (3x)
3H2O: H = 1 amu, O = 16 amu (2x)
Total mass = 56 + (3x35.5) + (3x1) + (2x16)
Total mass = 56 + 106.5 + 3 + 32
Total mass = 161 amu
Therefore, the correct answer is 161 amu.
