Homework Statement
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.
Homework Equations
The Attempt at a Solution
a) 110/24.7 = 4.45 ( i think that's 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!
