Finding the limiting reagent if 44.2 grams of P were reacted with 622 grams of Br2.
2P+3Br2=>2PBr3
First we find the GFW of each reactant.
GFW of P: 31
GFW of Br2: 160
Next we divide the number of grams of each reactant by the GFW.
44.2/31= 1.42
622/160= 3.88
Finally, we multiply each of the results by the coefficient of the other reactant/
1.42 x 3= 4.26
3.88 x 2= 7.775
Because 4.26 is smaller than 7.775, we know that the limiting reagent is P.
