Caffeine that is C8H10N402 is molecule which made up of 4 different elements. apart from carbon the other element includes
element symbol
nitrogen N
oxygen O
hydrogen H
The number of atom present in caffeine molecule are as follows
Nitrogen=4 atoms
Oxygen=2 atoms
Hydrogen=10 atoms
Density
=mass÷volume
=277÷38
=7.29 g/cm3
