The Haber process is the conversion of nitrogen and hydrogen at high pressure into ammonia, as follows: N2(g) + 3 H2(g) x g excess. 700 g = actual yield. 2 NH3(g) g = theoretical yield. If you must produce 700 g of ammonia, what mass of nitrogen should you use in the reaction, assuming that the percent yield of this reaction is 70%? actual yield.
