Answer:

199 g

Explanation:

Law of conservation of mass:

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

Explanation:

This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

For example:

In given reaction:

Reactant A = 115 g

Reactant B = 84 g

Product AB = ?

A + B → AB

115 g + 84 g = 199 g

199 g = 199 g
