Question

Determine the percent composition of nitrogen in ammonium chloride, NH4Cl. Round off your answer to the nearest hundredth of a percent.nswer to the nearest hundredth of a percent.

Answer 1

Answer:

26%

Explanation:

Molecular mass of NH4Cl= (Atomic mass of N) +4× (Atomic mass of H) + (Atomic mass of Cl)

                                              =(14)+4×(1)+(35.5)

                                              =53.5 amu

% of Nitrogen in NH4Cl = atomic mass of nitrogen divided by molecular mass of NH4Cl × 100 = 14/53.5 × 100 = 26.17% round to the nearest hundredth = 26%
