Answer : The volume of gas at STP is, 37.12 L
Explanation :
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,

where,
= initial pressure of gas = 922 torr = 1.213 atm
conversion used : (1 atm = 760 torr)
= final pressure of gas at STP = 1 atm
= initial volume of gas = 35.3 L
= final volume of gas at STP = ?
= initial temperature of gas = 315 K
= final temperature of gas at STP = 273 K
Now put all the given values in the above equation, we get:


Therefore, the volume of gas at STP is, 37.12 L
