Question

Calculate the molecular mass of the following is u 1) CH3 COOH. 2) NH3​

Answer 1

Answer:

Hey Mate!!

1) CH3COOH

2C, 4H, 2O

=> (2 × 12) + (4 × 1) + (2 × 16)

=> 24 + 4 + 32

=> 60 u

2) NH3

1N, 3H

=> (1 × 14) + (3 × 1)

=> 14 + 3

=> 17 u

Answer 2

Answer:

• Molecular mass of CH3 COOH is 60
• Molecular mass of NH3 is 17

Refer to the attachment for working.

• Important point:- Kindly learn all mass numbers of main elements.
• I also wrote the mass number of respective element in brackets.
