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 After asking my...
