The number of moles of gas in the sample is 0.0862 mol which can be calculated using ideal gas law.
An ideal gas is one that follows all the gas laws at every temperature and pressure condition. A real gas is referred to as a gas that does not act like an ideal gas.
From ideal gas equation, it is stated that
PV=nRT
Here, P represents the pressure of gas, V represents the volume of the gas, T represents the temperature, R is the gas constant and n is the number of moles.
It is given that, Volume of gas is 5.0 L, Pressure is 328 torr and the temperature is 37°C. The number of moles can be calculated as follows:
PV=nRT
328 torr*5.0 L=n*62.364 L Torr/mol/K*(32+273) K
n=328 torr*5.0 L/62.364 L Torr/mol/K*305 K
n=1640/19021.02 mol
n=0.0862 mol
Thus, the moles of gas are 0.0862 mol.
