Mass of 9 atoms of carbon = 9x12 amu = 108 u
Mass of 13 atoms of hydrogen = 13x1 amu =13 u Mass of 2.33 X${{10}^{-23}}$ g of other component
= (1 u)X(2.33 X${{10}^{-23}}$ g)/(1.66 x${{10}^{-24}}$g)
= 14.04 u
Molecular mass of the substance
= (108+ 13 +14.04 )u = 135.04 u
Mass of 13 atoms of hydrogen = 13x1 amu =13 u Mass of 2.33 X${{10}^{-23}}$ g of other component
= (1 u)X(2.33 X${{10}^{-23}}$ g)/(1.66 x${{10}^{-24}}$g)
= 14.04 u
Molecular mass of the substance
= (108+ 13 +14.04 )u = 135.04 u
