Answer:
1) NH₃
atomic mass of N = 14u
atomic mass of H = 1
molecular mass of NH₃ = 1 x 14 + 3 x 1 = 17u
2) CH₃COOH
atomic mass of C = 12
atomic mass of H = 1
atomic mass of O = 16
molecular mass of CH₃COOH = 2 x 12 + 4 x 1 + 2 x 16 = 60u
3) C₂H₅OH
atomic mass of C = 12
atomic mass of H = 1
atomic mass of 0 = 16
molecular mass of C₂H₅OH = 2 x 12 + 1 x 6 + 1 x 16 = 46u
