The relative molecular mass of sodium trioxonitrate, NaNO₃ is 85 g/mol.
The molecular mass of a substance is the sum of all atomic masses of all atoms in a molecule. It is measured in Dalton.
The compound is NaNO₃ and the atomic mass of all atoms are given below:
Atomic Mass of sodium (Na) = 23 g
Atomic Mass of nitrogen (N) = 14 g
Atomic Mass of oxygen (O) = 16 g
Now add the atomic masses of atoms of the molecules:
Molecular mass of = 23 +14 +16(3) = 85 g/mol.
Thus, the relative molecular mass of sodium trioxonitrate is 85 g/mol.
