1. The problem statement, all variables and given/known data Gas occupies 2m^3 at a pressure of 100kPa. What is the pressure when the volume is 1.5m^3 and the temprature is unchanged? 2. Relevant equations p=nRT/V 3. The attempt at a solution As a logic conclusion i took 1.5/2x100 and got 75 but 175 is not the answer.. The answer is 133kPa. I also tried the p=nRT/V. 22.4l=1mol so 1500/22.4x1 is 66.96mol. (66.96x22.4x0)/1500=0 Can someone please tell me how to calculate this type of problem? Thank you.
