Question

A gas has a volume of 25.0 mL when under a pressure of 525 Maggie. What is the new pressure when the volume has been increased to 86.2 mL while temperature remains constant?

Answer 1

The new pressure when the volume has been increased : 152.26 mmHg

Further explanation

Given

V₁ = 25 ml

P₁ = 525 Maggie ? (maybe you mean mmHg)

V₂ = 86.2 ml

Required

The new pressure

Solution

Boyle's Law

At a constant temperature, the gas volume is inversely proportional to the pressure applied

`\rm p_1V_1=p_2.V_2\\\\(p_1)/(p_2)=(V_2)/(V_1)`

`\tt P_2=(P_1.V_1)/(V_2)\\\\P_2=(525~mmHg* 25~ml)/(86.2~ml)\\\\P_2=152.26~mmHg`
