To calculate the total mass of the reactants, we need to add the individual masses of each element in FeCl3 and H2O.
FeCl3:
Fe: 56 amu
Cl: 35 amu (x 3) = 105 amu
H2O:
H: 1 amu (x 6) = 6 amu
O: 16 amu (x 3) = 48 amu
Total mass of reactants = mass of FeCl3 + mass of H2O
= (56 amu + 105 amu) + (6 amu + 48 amu)
= 161 amu + 54 amu
= 215 amu
Therefore, the total mass of the reactants is 215 amu.
In a chemical reaction, two molecules with a total mass of 76 amu react to form a single molecule. What is the mass of the molecule that is formed?(1 point)

In a chemical reaction, mass is conserved. This means that the total mass of the reactants is equal to the total mass of the products.
If two molecules with a total mass of 76 amu react to form a single molecule, the mass of the product must also be 76 amu. Therefore, the mass of the molecule that is formed is 76 amu.
