Answer;

= 36.217 mL

Explanation;

According to Charles' Law, the volume of a fixed mass of a gas is directly proportional to its absolute temperature at constant pressure.

Therefore;

V1/T1 = V2/T2

V1 = 17 mL, T1 = (-112 +273) = 161 K

V2 = ?  , T2 = (70 +273)=343 K

V2 = (17/161)× 343

    = 36.217 mL
