45 g of vinegar and 60 g of baking soda were used in a chemical reaction. What is the total mass of the products?

mass of product = 105 g

Explanation:

Using one of the law of chemical combination, the total mass of the product can be computed. The law of conservation of mass is used to solve this question. The law states that matter can neither be created nor destroyed. The law states that the mass of the reactant is equal to the mass of the product. The law enunciated the fact that the net change in mass of the reactant and product should be equal to zero.

Since the mass of the reactants is known the product mass can be computed using the law of conservation of mass.

Mass of the reactant = 45 g + 60 g

Mass of the reactant = 105 g

Since the mass of reactant is known, the mass of the product will be the same if you apply the law of conservation of mass.

Therefore,

mass of product = 105 g

105 g because 45 + 65 = 105
