No2 (nitrogen dioxide) and N2O4 (dinitrogen tetroxide) have the same empirical formula, NO2. Confirm this by calculating the percent by mass of each element present in the two compounds.

Question

N2O4= 92 g.

N2= 28g.

O4=64 g.

28/92 x100=30.4%

64/92x100=70%
----------------------------------------
NO2= 46g.

N=14 g.

O=32 g.

14/46x100=30.4%

32/46x100=70%
