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?

Sagot :

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  

[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]
