Hello, Brandy,
Rearrange the P1V1/T1 = P2V2/T2 relationship I described in an earlier answer, so that the unknown, P1 in this case, is separated:
P1 = P2(V2/V1)(T1/T2)
Then enter the data for all other variables. Be certain temperatures are in K, as they are here.
I get 1,661kPa, but check my calculations.

I figured it out. Thank you.

Can you help me with this one? The temperature of a sample of Br2 is changed without changing its volume, causing a change in pressure from 602.12 kPa to 762.15 kPa. If the starting temperature was 449.46 K, what is the final temperature in kelvins?

Yes, I can help, but the space here is too limited. Please post as a question. I can say that T2= T1(V2/V1)(P2/P1). You have everything you need to plug in the right side to find T2. I get 568.9K. The volumes cancel since they are the same (no change). So you don't need, nor are given, a volume. So it is just the ratio of pressures, (P2/P1) times T1. - Bob
