(adsbygoogle = window.adsbygoogle || []).push({}); HELP!!! Pressure Change for equation without volume

1. The problem statement, all variables and given/known data

A tank is pressurized with 5.0 atm of N2 and 10.0 atm of H2. Ammonia (NH3) is formed. When the pressure finally remains constant, indicating that the reaction has proceeded as far as it will go, the partial pressure of ammonia is 3.2 atm. What is the total pressure in the tank assuming that neither the temperature nor the volume of the container have changed?

2. Relevant equations

PV=nRT??

3. The attempt at a solution

I don't know how to go about this without using volume or number of moles. Is there another equation I should use??

Any help would be greatly appreciated
