Question

Helium gas occupies .125L at 760 mmHg. What will the volume be if the pressure is increased to 820mm Hg

Answer 1

115.8L

Explanation:

use formula PV=constant

Answer 2

Answer:

According to Boyle's law,

P₁V₁ = P₂V₂

Here,

P₁ = 760 mm Hg

V₁ = 125L

P₂ = 820 mm Hg

V₂ = ?

P₁V₁ = P₂V₂

By solving we get,

V₂ = 115.85 L
