mass of the gas = 10 g

<h3>Further explanation</h3>

<em>The law of conservation of mass :</em>

<em>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.</em>

Reaction

$\tt X+Z\rightarrow gas+solution$

mass before reaction=mass after reaction

$\tt 25+60=gas+75\\\\gas=25+60-75=10~g$
