A sample of gas occupies a volume of 145ml at 560 torr and 20°C. Calculate the new pressure if it's volume increased to 290ml at the same temperature.​

Sagot :

Given:

[tex]P₁ = \text{560 to rr}[/tex]

[tex]V₁ = \text{145 m L}[/tex]

[tex]V₂ = \text{290 m L}[/tex]

Required:

[tex]P₂[/tex]

Solution:

[tex]P₁V₁ = P₂V₂[/tex]

[tex]P₂ = P₁ × \frac{V₁}{V₂}[/tex]

[tex]P₂ = \text{560 to rr} × \frac{\text{145 m L}}{\text{290 m L}}[/tex]

[tex]\boxed{P₂ = \text{280 to rr}}[/tex]
