Combined Gas Law Help- Check Answer

From the word problem, I got
V1=2.00L, P1=5.00ATM, T1=127 Celsius (400.15K), V2= 10.0L, P2=? , T2= 27.0 Celsius (300.15K)

So for P2 I got .750 Atm. Please Verify.

You are correct.

P1V1T2 = P2V2T1

5.0atm x 2.0L x 300.15K = P2 x 10L x 400.15.

P2 = (5 x 2 x 300.15) / 10 x 400.15

3001.5 / 4001.5 = 0.750 atm.
