Calculate the pressure-volume work for the given reaction

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

 

[Borek]

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?
