The constant Kp for the dissociation of dinitrogen tetraoxide N204 at 25C. is equal to 0.141at. Calculate at said temperature the concentration of NO2 in equilibrium with 0.0072 moles of N204 existing in a container with a capacity of 0.250 liters. Find the pressure and density of the gas mixture. Reaction: N204 = NO2 (20points)

perform all the steps, I know nothing and I want to learn everything. Document everything, how did you get to the solution, please, I don't know anything
