1. The problem statement, all variables and given/known data A 200g sample of CO2 occupies a volume of 110 L at a pressure of 1 atm. a) What is the number of moles in the gas b) What is the temperature? c) if the volume is increased up to 200 L and the temperature is kept constant. what is the new pressure. 2. Relevant equations 3. The attempt at a solution a) 110/24.7 = 4.45 ( i think thats right) b) pV = constant is that constant the temperature??? if so the temperature = 1 x 110 = 110 c) ( p1 v1 ) / T1 = ( p2 V2 ) / T2 (1 x 110) / 110 = ( p2 x 200) / 110 p2 = (1 x 110 x 110) / (110 x 200) = 0.55 i'm not sure if i'm doing this right can anyone help? THANKS!
