Please work out the problem from scratch. A "solution" has already been posted for this question before on Chegg, but it is very incorrect. Please do not just post the same incorrect solution that was done before. Thank you for your help.

4) Ammonia is partially dissociated in the gas phase according to the reaction NH3(g)21N2(g)+23H2(g) A mass of 0.295g of NH3 is placed in a 500cm3 container at 500.0K and dissociates to an equilibrium mixture at 5.6 bar. What are the mole fractions of NH3,N2 and H2 ? Assume 56% of the NH3 has dissociated and that the gases are ideal
