A sample of carbon dioxide at 10.0 ° C has a volume of 300.0 mL at 760 torr. What is the volume of the gas at 30.0 ° C and 760 torr?
A) 275 mL
B) 280.5 mL
C) 321.2 mL
D) 755 mL
E) 900 mL

Using the combined gas law:

(P1V1)/T1 = (P2V2)/T2

We can rearrange the equation to solve for V2:

V2 = (P1V1T2)/(T1P2)

Plugging in the values:

V2 = (760 torr x 300.0 mL x 303.15 K)/(283.15 K x 760 torr)

V2 = 321.2 mL

Therefore, the answer is choice C, 321.2 mL.
