A sample of gas had a volume of 20.0 liters at 0°C and 1520 torr. What would be the volume of this

gas sample at 0°C and 760 torr?

V

=

Ti =

P

=

V2 =

T2 =

P2=

V2 =

40 L

Explanation:

Given dа ta:

Initial volume = 20.0 L

Initial pressure = 1520 torr

Final volume = ?

Final pressure = 760 torr

Solution:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = Initial volume

P₂ = Final pressure

V₂ = Final volume

Now we will put the values in formula.

P₁V₁ = P₂V₂

1520 torr * 20.0 L = 760 torr * V₂

V₂ = 30400 torr. L / 760 torr

V₂ = 40 L
