Answer 1

Answer:

n the reaction between phosphoric acid and ammonia, a compound forms containing 28.2 grams nitrogen, 8.1 grams hydrogen, 20.8 grams phosphorus, and 42.9 grams oxygen by mass. a. ... 20.8 g P x 1 mol P = 0.672 mol P 30.97 g P 42.9 g O x 1 mol O = 2.69 mol O 16.00 g O Step 2: 2.01 mol N = 2.991 mol of N = 3 mol .
