Calculate the pressure exerted by one gram of helium present in a 5 L vessel at room temperature?

Text Solution

Verified by Experts

The ideal gas equation is given as, PV=nRT
Number of moles `= n = 1/4 = 0.25`
R = Universal gas constant `= 0.0821 L atm K^(-1) mol^(-1)`
V=Volume = 5 lit
Pressure exerted by helium gas
`P = (nRT)/(V) = (0.25 xx 0.0821 xx 298)/(5)`
` = 1.224 atm = 930 ` torr
