Answer :-
The gas 'x' will occupy a volume of 42 litres at 500 mm Hg .
Explanation :-
We have :-
→ Initial volume = 30 L
→ Initial pressure = 700 mm Hg
→ Final temperature = 500 mm Hg
→ Temperature is constant .
________________________________
By Boyle's law, we have :-
P₁V₁ = P₂V₂ [ T is constant ]
Where :-
• P₁ is initial pressure .
• V₁ is initial volume .
• P₂ is final pressure .
• V₂ is final volume .
Substituting values, we get :-
⇒ 30 × 700 = 500 × V₂
⇒ 21000 = 500V₂
⇒ V₂ = 21000/500
⇒ V₂ = 42 L

Given :-
A gas 'x' occupies 30L at 700mmHg
To Find :-
Volume of it will occupy at 500mmHg assuming temperature to be constant.
Solution :-
We know that
Pressure is constant to volume
P₁V₁ = P₂V₂
V₂ = P₁V₁/P₂
V₂ = 30 × 700/500
V₂ = 30 × 7/5
V₂ = 6 × 7
V₂ = 42 L
