how many grams of NH3 can be prepared from 85.5 grams of N2 and 17.3 grams of H2 ?

N2 + 3H2 ---> 2NH3mass of N2 = 28gmass of H2 = 2gmass of NH3 = 17gaccording to the reaction:28g N2----------------- 3*2g H285,5g N2-------------------- xx = 18,32g H2 >>>  so, nitrogen is excessaccording to the reaction:2*3g H2---------------------- 2*17g NH317,3g H2 ------------------------- xx = 98,03g NH3answer: 98,03g of NH3
