The molecular formula shows the actual number of atoms of each element present in a compound. The molecular formula is different for different compounds.
The molecular formula of the given compound in the question is [tex]N_2O_4[/tex]
An empirical formula is calculated first to find the molecular formula. First, let us calculate the empirical formula for the compound.
The data given in the question is as N is 0.606g and O is 1.390g
After solving the equation,
[tex]N = \frac{0.606}{14} = 0.0432\\\\O =\frac{1.390}{16} = 0.0869[/tex]
Divide it by the smallest outcomes
[tex]N = \frac{0.0432}{0.0432} = 1\\\\O = \frac{0.0869}{0.0432} = 2[/tex]
The empirical formula is NO2. Now we have to find the molecular formula.
[tex][NO2]n = 92[14 + (16x2)]n = 92[14 +32]n = 9246n = 92[/tex]
After solving the equation the value of 'n' is 2.
Hence, The molecular formula
[tex][NO2]n \\= [NO2]2\\ = N2O4[/tex]
