2NO2(g) <=> N2O4(g)

138g of N2O4 were put into a vessel of volume 4.00 dm^3. At
equilibrium 17.25g of NO2 were present. Calculate
a) the no. of moles initially present and the no. of moles of NO2 at
equilibrium
b)the no. of moles of each component at equilibrium
C)the total no. of moles of all components present
d)the fractions of each
e)if the total pressure is 10^6Pa the partial pressure of each
f)Kp for equilibrium
g) use your data from b) to find the concentration of each component
in mol dm^(-3)
h)find Kc for this equilibrium
