A sample of nitrogen gas has a volume of 32.4 L at 20°C. The gas is heated to 220ºC at constant pressure. What is the final volume of nitrogen?
A)2.94 L
B)19.3 L
C)31.4 L
D)54.5 L
E)356 L

Using Charles's Law (V1/T1 = V2/T2), we can calculate the final volume of nitrogen:

V1 = 32.4 L (initial volume)
T1 = 20°C + 273 = 293 K (initial temperature in Kelvin)
T2 = 220°C + 273 = 493 K (final temperature in Kelvin)

V2 = V1(T2/T1) = 32.4 L (493 K/293 K) = 54.5 L

Therefore, the final volume of nitrogen is 54.5 L.
