Answer to Question #80572 in General Chemistry for Alphonse Wena

Question

Ammonium nitrate (NH4NO3) is an important nitrogen containing fertilizer.
What is the percentage (%) composition of nitrogen (N) in one mole of ammonium nitrate?
Given the atomic masses:
N = 14, H = 1, and O = 16

Answer 1

Answer:
Formula: w%= (mN x 100 %) / (mN + m¬¬H + mO) therefore
w%= (2 x 14 x 100 %) / ((2 x 14) + (4 x 1) + (3 x 16)) = 35 %
so w% = 35 % N in one mole ammonium nitrate.
