Solving a problem in chemistry section 11 point 39

39. The mixture of nitrogen and hydrogen is introduced into the apparatus for the synthesis of ammonia. The resulting output mixture of gases in volume 1,344 liters (eg. In.) Passed over red-hot copper oxide (II), and the mass of the tube with copper oxide (II) decreased by 0.96, the remaining gas mixture is then passed over phosphorus pentoxide, received output 0.448 liters of gas (eg. in.). The composition of the gas mixture taken for ammonia synthesis (in mole) and the yield of ammonia.
