Answer is: volume of the sample is 36,2 mL.

V₁ (sample) = 17 mL.

T₁ (sample) = - 112°C = - 112 + 273,15 = 161,15 K.

T₂ (sample) = 70°C = 70 + 273,15 = 343,15 K.

V₂ (sample) = ?

Charles' Law: V₁/T₁ = V₂/T₂.

17 mL/161,15 K = V₂/343,15 K.

161,15 K · V₂ = 17 mL · 343,15 K

V₂ = 5833,55 K·mL : 161,15 K

V₂ = 36,2 mL.
