A gas initially at STP is heated to 50°C keeping the volume constant. What is its new pressure?

I used this formula:

P1 = 1 atm

T1 = 273 K

T2 = 323 K

solve for P2

P2 = P1 (T2/T1)

But, where do I use the 50 degrees C?

Also, is my answer correct:

P2 = 1atm x 323K/273K = 1.18 atm

Yes, your answer is correct. The 50 C is the 323 K.
