Some very effective rocket fuels are composed of lightweight liquids. The fuel composed of dimethylhydrazine [(CH3)2N2H2] mixed with dinitrogen tetroxide was used to power the lunar lander in its missions to the moon. The two components react according to the following equation: (CH3)2N2H2(l) 1 2N4O4(l) 88n 3N2(g) 1 4H2O(g) 1 2CO2(g) If 150 g of dimethylhydrazine reacts with excess dinitrogen tetroxide and the product gases are collected at 278C in an evacuated 250-L tank, what is the partial pressure of nitrogen gas produced and what is the total pressure in the tank assuming the reaction has 100% yield?
