Two different formulas are used in order to represent composition of any miolecule, empirical formula and molecular formula . While the fomer gives an idea of relative ratio of number of atoms, latter gives the exact number of atoms in the molecule.
An organic compound contains C N and O . The number of oxygen atom is same as that of nitogen atom which is one third of number of carbon atoms and number of hydrogen atoms is approximately 2.33 times of carbon atoms. If vapour density of the compound is 73 then molecular formula of the compound will be :

`C_(3)H_(7)NO`

`C_(2)H_(5)NO`

`C_(6)H_(14)N_(2)O_(2)`

`C_(5)H_(12)N_(3)O_(2)`

Two different formulas are used in order to represent composition of any miolecule, empirical formula and molecular formula . While the fomer gives an idea of relative ratio of number of atoms, latter gives the exact number of atoms in the molecule. A 62 gm sample of a substance consist of 2 gm hydrogen , 28 gm nitrogen and remaining oxygen . What will b its empirical formula?

`NHO_(2)`

`NHO_(4)`

`NHO_(3)`

`NHO_(4)`

`CH_(3)`

`C_(2)H_(6)O`

`CH_(2)O`

`CH_(2)`
