0.326 moles of gas
Explanation:
Knowing the volume of a gas at standard temperature and pressure (STP) we may calculate the number of moles of the gas using the following formula:
number of moles = volume / 22.4 (L /mole)
number of moles of gas = 7.3 (L) / 22.4 (L /mole)
number of moles of gas = 0.326 moles
