Homework Statement
Assume that 2.00 moles of water are formed according to the following reaction at constant
pressure (101.3 kPa) and constant temperature (298 K):
I have to calculate the pressure-volume work for the given reaction and i really dont know how to start or what to use. Can someone help me?
Relevant Equations
2 H2(g) + O2(g) --> 2 H2O(l)
I dont have an solution Attempt. Maybe something with PV=nRT but this is for ideal gas and H2O is liquid. An other formula they introduced us to is: dE=-P*V

If it is about work more like P*dV.

What is the initial volume of the mixture, and what is the final volume?

That's the problem. I dont have more information. I wrote down everything i got.

You have everything you need. What is volume of water produced? What reacted?
