A gas is produced when 25 g of substance X is mixed into 60 g of solution Z in a beaker. The mass of the solution in the beaker after the reaction is 75 g. What is the mass of the gas released? (X + Z -> gas + solution)

mass of the gas = 10 g

The law of conservation of mass :

In a closed / isolated system, the total mass of the substance before the reaction will be equal to the total mass of the reaction product.

Reaction

mass before reaction=mass after reaction
