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?
To find the total mass of the reactants, we need to calculate the molar mass of each reactant and then add them together.
FeCl3:
Fe: 56 amu
Cl: 35 amu x 3 = 105 amu
Total mass of FeCl3 = 56 + 105 = 161 amu
H2O:
H: 1 amu x 2 = 2 amu
O: 16 amu
Total mass of H2O = 2 + 16 = 18 amu
Total mass of reactants = Total mass of FeCl3 + Total mass of H2O
Total mass of reactants = 161 amu + 18 amu
Total mass of reactants = 179 amu
Therefore, the total mass of the reactants is 179 amu.
