Find the limiting reagent if 99.6 grams of NH3 were reacted with 473 grams of O2.
4NH3+5O2=>4NO+6H2O
First we find the GFW of each reactant.
GFW of NH3: 17
GFW of O2: 32
Next we divide the number of grams of each reactant by the GFW.
99.6/17= 5.85
437/32= 13.65
Finally, we multiply each of the results by the coefficient of the other reactant/
5.85x5= 29.25
13.65x4= 54.6
Because 29.25 is smaller than 54.6, we know that the limiting reagent is NH3.
