A sample of a gas at STP has its temperature raised to 510C and its pressure raised to 5 atm. If the initial volume of this gas is 100.0 ml, what will the final volume be?

(P1V1/T1) = (P2V2/T2)
Remember T must be in kelvin.

is the answer .98?

0.98 WHAT? No it isn't. If you will post your work I'll find the error.

You have no T1 in your equation. You have not converted 510 C to kelvin for T2.
You have the equal sign in the wrong place. Substituee into the equation as is. Don't rearrange it until all of the numbers are in.
(P1V1/T1) = (P2V2/T2)
Write the down so you can follow what you're doing.
P1 = 1 atm
V1 = 100 mL
T1 = 273

what do i plug in for v2 and p2 then?
- Chemistry - DrBob222, Sunday, May 13, 2012 at 10:28pm
Are we reading the same problem?
P1 = 1 atm (STP is standard T and P which is 273 for T and 1 atm for P)
V1 = 100 mL in the problem.
T1 = 273STP again.
P2 = 5 atm from the problem.
V2 = this is what you are to calculate.
T2 = 510 converted to kelvin.
