Constant pressure = Charles' Law
V1/T1 = V2/T2
V1 = 4.60 L
T1 = 21.0 ºC + 273 = 294K
V2 = 2.30 L
T2 = ?
V1/T1 = V2/T2
(4.60 L)/(294 K) = (2.30 L)/T2
T2 = 147 K = -126ºC

Can you explain how you did that last step of 4.6 diveded by 294 = 2.30 diveded by T2

The last step derives from the original equation of V/T1 = V2/T2. Just plug in the numbers: 4.60/294 = 2.30/T2. Cross multiply to get
4.60 T2 = 294 x 2.30. Then T2 = (294)(2.30)/4.60 and T2 = 147K
