Using the law of conservation of mass, what is the mass, in grams, of the product in the given reaction?

Reactant 1 (35 grams)+ Reactant 2 (115 grams) →Product (? grams)
a. 140
b. 80
c. 150
d. 75

1 answer

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction. Therefore, the total mass of the reactants is equal to the total mass of the products.

Reactant 1 (35 grams) + Reactant 2 (115 grams) = Product (x grams)

The total mass of the reactants is 35 grams + 115 grams = 150 grams.

Therefore, the mass of the product is 150 grams.

Answer: c. 150
