a sample of gas occupies 1910ml at 22.8 degrees C and 740 torr. what volume would it occupy at the same pressure and 285 degrees C? answer units in ml

DrBob222,
(P1V1/T1) = (P2V2/T2) but since pressure is the same, you can strike that from the equation.
Remember to convert T to kelvin.

ALISON,
You have to use the combined gas law.
(V1)(P1) / T1 = (V2)(P2) / T2
AND YOU PLUG YOUR GIVEN INTO THE EQUATION.
(1910ML)(740TORR) / 22.8 = (V2)(740TORR) / 285DEGREES
AND SOLVE FOR V2.
