9. A gas occupies 8.2 L at 48°C and 750. torr. What volume will the gas occupy at STP?

The volume the gas will occupy at STP is 6.9 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 = 750 torr = 0.99 atm  (760torr=1atm)

= final pressure of gas = 1 atm (at STP)

= initial volume of gas = 8.2 L

= final volume of gas = ?

= initial temperature of gas =

= final temperature of gas = (at STP)

Now put all the given values in the above equation, we get:

Thus volume the gas will occupy at STP is 6.9 L
