Given:
V (NH3) = 4.48 l.
To find:
N (H) =?.
Decision:
n (NH3) = V (NH3) / Vm;
n (NH3) = 4.48 / 22.4 = 0.2 mol.
N (NH3) = n * Na;
N (NH3) = 0.2 * 6.02 * 10 ^ 23 = 1.204 * 10 ^ 23 molecules.
N (H) = N (NH3) * 3;
N (H) = 3 * 1.204 * 10 ^ 23 = 3.612 * 10 ^ 23 atoms.
Answer: N (H) = ~ 3.6 * 10 ^ 23 atoms.
