Use the equation and the table to answer the question. FeCl3 + 3H2O → Fe(OH)3 + 3HCl Element Mass of an Atom (amu) Fe 56 Cl 35 H 1 O 16 Iron chloride and water react according to the equation shown. The table shows the atomic masses of the elements involved in the reaction. What is the total mass of the reactants? (1 point) Responses 215 amu 215 amu 161 amu 161 amu 179 amu 179 amu 108 amu
To find the total mass of the reactants, you need to calculate the sum of the atomic masses of each element in the reactants.
FeCl3:
Fe = 56 amu
Cl = 35 amu x 3 = 105 amu
Total mass of FeCl3 = 56 amu + 105 amu = 161 amu
H2O:
H = 1 amu x 2 = 2 amu
O = 16 amu
Total mass of H2O = 2 amu + 16 amu = 18 amu
Total mass of FeCl3 + H2O = 161 amu + 18 amu = 179 amu
Therefore, the total mass of the reactants is 179 amu.
