To determine the total mass of the reactants, we need to calculate the sum of the atomic masses of the elements in FeCl3 and H2O.
FeCl3:
Fe: 1 atom x 56 amu = 56 amu
Cl: 3 atoms x 35 amu = 105 amu
H2O:
H: 6 atoms x 1 amu = 6 amu
O: 3 atoms x 16 amu = 48 amu
Total mass of FeCl3 and H2O = 56 amu + 105 amu + 6 amu + 48 amu = 215 amu
Therefore, the correct answer is:
215 amu
FeCl3:
Fe: 1 atom x 56 amu = 56 amu
Cl: 3 atoms x 35 amu = 105 amu
H2O:
H: 6 atoms x 1 amu = 6 amu
O: 3 atoms x 16 amu = 48 amu
Total mass of FeCl3 and H2O = 56 amu + 105 amu + 6 amu + 48 amu = 215 amu
Therefore, the correct answer is:
215 amu
