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...
