A sample of hydrogen has an initial temperature of 122.0 °F. When the temperature is lowered to -23.0 °F, the volume of hydrogen becomes 212 cm3. What was the initial volume of the hydrogen?

The initial volume of gas was

Explanation:

Charles's Law: This law states that volume is directly proportional to temperature of the gas at constant pressure and number of moles.

    (At constant pressure and number of moles)

where,

= initial volume of gas   =?

= final volume of gas =  

= initial temperature of gas  =    

= final temperature of gas  =

Therefore, the initial volume of gas was
