OH!
w= -nRT ln (P2/P1)
So the P1 is atmospheric pressure and for the P2 I use PV=nRT
Then I have both pressures and it's just plug and chug from there.
Homework Statement
A quantity of 4.50 g CaC2 is reacted with an excess of water at 298K and atmospheric pressure.
CaC2 (s) + 2 H2O (l) --> Ca(OH)2 (aq) + C2H2 (g)
Calculate the work done in Joules by the Acetylene gas against the atmospheric pressure.[/B]Homework Equations
