Question

2) Calculate molecular mass of Ammonia and Acetic Acid

​

Answer 1

Answer:

The molecular weight of ammonia is = [14 + (3×1)] = 17. ... The molecular weight of acetic acid = [(12×2) + (4×1) + (16×2)] = 60. The molecular weight of acetaldehyde = [(12×2) + (4×1) + 16] = 44. Notes: The molecular weight of the substance is the weight of one molecule of that compound in atomic mass units.

Answer 2

Answer:

The molecular weight of ammonia is = [14 + (3×1)] = 17. The molecular weight of chlorine is = [35.5×2] = 76. The molecular weight of acetic acid = [(12×2) + (4×1) + (16×2)] = 60. The molecular weight of acetaldehyde = [(12×2) + (4×1) + 16] = 44

i hope you correct answer
