Ideal Gas Problem given volume and temperature
« on: November 17, 2019, 09:42:39 AM »
On my lab assignment, I was given the question, "A sample of gas has a volume of 5.33L at a temperature of 112°C, determine the temperature (in Kelvin) at which it will have a volume of 7.32L


After attempting to put the values given into the equation P1V1/T1=P2V2/T2
The equation with substituted numbers looked like:

(1atm)(5.33L)/385.15K=(1atm)(7.32L)/T2 
And solving for T2 It was  T2 = (1atm)(5.33L)/(385.15K)(1atm)(7.32L)

I ended up with 0.00189 K which, I'm guessing, is not the right answer.

I'm wondering if I set it up wrong, or there are some values from the STP conditions that I didn't include, or something else. If someone could help me with this, it would be greatly appreciated. Thank you.

Hard to tell what you did wrong not seeing the numbers. Can be anything.

The volume is less than 40% larger and the temperature should be higher by about 150 degrees.

Recheck the algebraic part.

You've calculated 1/T2.
