Question

Find the molecular mass of HNO₃.
( At. mass : H = 1, N = 14, O = 16 ) *​

Answer 1

Answer:

63

Explanation:

Molecular weight of H=1

                                    N=14

                                    O=16

        1++14+3(16)=15+48=63

hope this helps you

Answer 2

Answer:

63 u

Explanation:

The molecular mass of HNO3 = the atomic mass of H+ the atomic mass of N+3* the atomic mass of O

=1+14+48=63u

Hope it helps
