Question

In a chemical reaction, the total mass of the reactants is 50 g. What will be the total mass of the products formed?

a) 40 g
b) 100 g
c) 50 g
d) 25 g

Answer 1

The correct answer is c) 50 g.

• According to the law of conservation of mass, matter is neither created nor destroyed during a chemical reaction. Hence, the total mass of the reactants will be equal to that of the products.
• If the mass of the reactants is given to be 50 g, then the mass of the products will also be 50 g.
