Question

calculate the relative molecular mass of water
calculate the relative molecular mass of HNO (down) 3
mass H=1, N=14, O=16​

Answer 1

Answer:

63u.

Explanation:

Given,

Atomic mass of H = 1u

Atomic mass of N = 14 u

Atomic mass of O = 16u

The molar mass of HNO3 is

(1 × 1) +(1 × 14) + (16×3) = 63 u.

Answer 2

Answer:

Molecular mass of HNO

3

is the sum of the atomic masses of H,NO

So 1+14+16×3=63 u.
