Hey Dear,

◆ Answer -

(a) Molar mass of NH3 = 17 amu

(b) Molar mass of CH3-COOH = 60 amu

(c) Molar mass of C2H5-OH = 46 amu

● Explanation -

Before we start calculating, I'd like to write down atomix masses of relevant individual elements -

H => 1 amu

C => 12 amu

N => 14 amu

O => 16 amu

# Calculations -

(a) NH3 -

Molar mass of NH3 = 14 + 3×1

Molar mass of NH3 = 17 amu

(b) CH3-COOH -

Molar mass of CH3-COOH = 2×12 + 4×1 + 2×16

Molar mass of CH3-COOH = 60 amu

(c) C2H5-OH -

Molar mass of C2H5-OH = 2×12 + 6×1 + 16

Molar mass of C2H5-OH = 46 amu

Hope that's helpful...
