For this problem, we could use the Charles's law:
[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]We could replace the values that the question gives to us:
[tex]\frac{7.41L}{418.55K}=\frac{2.59L}{T_2}\to T_2=\frac{418.55K\cdot2.59L}{7.41L}=146.29K[/tex]Therefore, the new temperature of the gas is 146.29K.
