The new pressure when the volume has been increased : 152.26 mmHg
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
[tex]\rm p_1V_1=p_2.V_2\\\\\dfrac{p_1}{p_2}=\dfrac{V_2}{V_1}[/tex]
[tex]\tt P_2=\dfrac{P_1.V_1}{V_2}\\\\P_2=\dfrac{525~mmHg\times 25~ml}{86.2~ml}\\\\P_2=152.26~mmHg[/tex]
