The molecular weight of the substance = Sum of atomic masses of the elements present in a molecule.

= (Number of atoms of different elements x atomic mass of each elements)

Firstly, calculate the number of  atoms of the other component. as follow:-

Number of moles of other component = (Given mass of the components/molar mass)

Number of atoms of other component = Number of moles x 6.023 x1023

Molecular weight of the substance =[(12 x9) +(13 x 1) + (Number of atoms of other component x atomic mass)]
