Question

Calculate the molecular mass of nitric acid, HNO3. (Atomic masses H = 1 u ; N = 14 u ; O = 16 u)

Answer 1

Answer:

HNO3=

1+14+16×3

1+14+48

15+48

63

Answer 2

HNO3 = 63u

Explanation:

Given ,

H = 1 u

N = 14 u

O = 16 u

Molecular mass of nitric acid (HNO3), adding all the given value,

=$\left \{ ( 1\times 1) + ( 1\times 14) + ( 16\times 3) \right \}\times {u}$

=$63\times {u}$

Molecular mass of nitric acid is 63 u.
