Answer:

75g

Explanation:

Given parameters

Mass of product = 375g

Mass of reactant X = 300g

Unknown:

Mass of reactant Y = ?

Solution:

To solve this problem, we need to understand the law of conservation of mass. The law states that "matter is neither created nor destroyed in a chemical reaction".

So;

Mass of X + Mass of Y = Mass of product

Mass of Y = Mass of product - Mass of X

Mass of Y = 375 - 300 = 75g
