A sample of an ideal gas has a volume of 3.20 L at 14.80 °C and 1.50 atm. What is the volume of the gas at 21.80 °C and 0.989 atm?

1 answer

the volume is directly proportional to the (absolute) temperature (ºK)

and inversely proportional to the pressure

v = 3.20 L * (1.50 / .989) * [(21.80 + 273) / (14.80 + 273)]
