A sample of gas at 57oC and 1.02atm occupies a volume of 2.20L. What volume would this gas occupy at 107oC and 0.789atm?

Answer 1

(p1v1/t1) = (p2v2/t2)
Remember T must be in kelvin.

Answer 2

1.06atm x 1.25L/250.0K
1.325/250.0K
m=.0053

Answer 3

I don't understand anything you wrote. Are you working this problem or another one? Plug values into that equation I gave you and solve. What you have posted is gibberish.
