Explanation :
According to the Charles's law, the volume of a gas is directly proportional to the temperature of the gas at constant pressure and the number of moles of gas.
V\propto TV∝T
or,
\frac{V_1}{V_2}=\frac{T_1}{T_2}
V

where,

= initial volume of gas = 524cm^3524cm

V_2V

= final volume of gas = ?
T_1T
1
= initial temperature of gas = 491 K
T_2T
2
= final temperature of gas = 297 K
Now put all the given values in the above formula, we get the final volume of a gas.
\frac{524cm^3}{V_2}=\frac{491K}{297K}
V

=
297K
491K
V_2=316.96cm^3V

=316.96cm

Therefore, the final volume of a gas is, 316.96cm^3316.96cm
