Answer 2

Answer and Explanation:

The molecular mass is the mass of a given molecule: it is measured in daltons. Different molecules of the same compound may have different molecular masses because they contain different isotopes of an element.

( ◍•㉦•◍ )        (*✧×✧*)         (^◕.◕^)

Molecular mass of HNO3  is the sum of the atomic masses of H,NO

So 1 + 14 + 16 × 3 = 63 u.
