Question

A 21.0-L sample of nitrogen at 7.40 atm and 24 Celcius is simultaneously expanded to 56.2 L and heated to 38 Celcius. What is the new pressure of the gas?

Answer 1

You are given an initial volume (21.0 L), an initial pressure (7.40 atm) and an initial temperature (24ºC = 297ºK). You are also given a final volume (56.2 L) and temperature (38ºC = 311ºK) and are asked to find the final pressure. Do you recall learning P1V1/T1 = P2V2/T2.

Simply use this equation and solve for P2.  You should get an answer of 2.90 atm
