Answer: 38.6 ml
Explanation:
Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.
[tex]V\propto T[/tex] (At constant pressure and number of moles)
[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]
[tex]V_1[/tex]= initial volume = 17 ml
[tex]V_2[/tex]= final volume = ?
[tex]T_1[/tex]= initial temperature =[tex]-122^0C=273+(-122)=151K[/tex]
[tex]T_2[/tex]=final temperature=[tex]70^0C= 70+273=343K[/tex]
[tex]\frac{17}{151}=\frac{V_2}{343}[/tex]
[tex]V_2=38.6ml[/tex]
Thus final volume is 38.6 ml at 70[tex]^0C[/tex]
