Thank you for the opportunity to help you with your question!

from the law of volumes (Charles law ), V/T = k

this implies that V1 / T1 =V2 / T2

V1 = 2.35l, T1 =20.0C = 293.0k

V2 = ?, T2 = -5.00C = 268.0k

where k -kelvin

making V2 the subject we have V2= (V1/T1)*T2

V2 =  2.35/293 * 268

V2 = 2.15L

this is the new volume that the gas will occupy at -5.00C

Please let me know if you need any clarification. I'm always happy to answer your questions.
