Question

A 70.0 L sample of gas at 20.0ºC and 600. mm Hg expands to 90.0 L at 15.0ºC. What is the new gas pressure?

Answer 1

\[\frac{ P1V1 }{ T1 } = \frac{ P2V2 }{ T2 }\]

Answer 2

convert mm Hg to atm
and convert temperature to Kelvin

Answer 3

P1= 600. mm Hg = convert to atm
V1= 70.0 L
T1= 20.0ºC = convert to Kelvin

V2= 90.0 L
T2 = 15.0ºC= convert to Kelvin

P2 = X
so find it
