The Ideal Gas Equation

At 0∘C and 76...

Question

At 0^∘C and 760 mm Hg pressure, a gas occupies a volume of 100 cm3. The temperature Of the gas is increased by one fifth and the pressure is increased one and a half times. Calculate the final volume of the gas.

Open in App

Solution

T1= 273 K or 0°C
P1=760 mm of Hg
V1=100 cm3
T2=273+(15×273=327.6 K
P2=760+ (1+12)×760=760 + 32×760 = 1900 mm of Hg
V2=?
Combined Gas Law :
P1V1/T1=P2V2/T2
V2=760×100×327.61900×273
V2= 48 cm3
