Answer
The mass of the reactants is: 0.500 + 0.701 = 1.201 g. And the mass of the products is: 0.855 + 0.346 = 1.201g.
Work Step by Step
According to the law of mass conservation, the total mass of the reagents must be the total mass of the products.
We know the masses of the compounds through the previous exercises. Therefore, the mass of the reactants is: 0.500 + 0.701 = 1.201 g. And the mass of the products is: 0.855 + 0.346 = 1.201g.
