A sample of gas collected at 21.0 $\circ$ C and a pressure of 660 torr has a volume of 1.83 liters.What volume in liters will the gas occupy at 38.0 $\circ$ C under a pressure of 500 torr?
A) 2.56
B) 4.37
C) 2.28
D) 1.33

Using the combined gas law, $ V_2 = V_1 \times \frac{P_1}{P_2} \times \frac{T_2}{T_1} $, where $ T $ is in Kelvin. Converting temperatures to Kelvin and substituting the values gives $ V_2 = 1.83 \times \frac{660}{500} \times \frac{311}{294} \approx 2.56 $ liters.
