Conservation in Chemical Reactions Quick Check 3 of 43 of 4 Items Question 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 108 amu 108 amu 179 amu 179 amu 161 amu
The total mass of the reactants can be calculated by adding up the atomic masses of each element in the reactants:
FeCl3: Fe (56 amu) + Cl (35 amu) x 3 = 161 amu
3H2O: H (1 amu) x 6 + O (16 amu) x 3 = 54 amu
Total mass of the reactants = 161 amu + 54 amu = 215 amu
Therefore, the total mass of the reactants is 215 amu.
