Question

A helium balloon in a closed car occupies a volume of 2.32 L at 40.0oC. How many moles of helium would exert 5 atm of pressure at the ideal conditions above?

Answer 1

.451 mole

Step-by-step explanation:

PV = n RT R = gas constany = .082057 L-Atm/K-mol T is in units Kelvin

5 *2.32 = n (.082057)(40+273.15)

n=.451 mole
