Answer : The final temperature of gas will be, 149 K
Explanation :
Charles' Law : It is defined as the volume of gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

or,

where,
= initial volume of gas = 1.55 L
= final volume of gas = 753 ml = 0.753 L
= initial temperature of gas = 
= final temperature of gas = ?
Now put all the given values in the above formula, we get the final temperature of the gas.


Therefore, the final temperature of gas will be, 149 K
