How do you solve for V1 in a Combined Gas Law problem?

(1/1)

mydiamond:
Hello!
I was just wondering what the formula would be to solve for V1 when working on a Combined Gas Law problem. If somebody could help me, that would be great!
Thank you!

hummingbird:
P1V1 / T1 = P2V2 / T2

rearranging...
V1 = V2 x (P2 / P1) x (T1 / T2)

erika:
Depending on what you DO KNOW you set it up like so
P1V1=P2V2
for V1=P2V2/P1
for temp its
V1/T1=V2/T2
V1=V2T1/T2
