How can i calculate the mass percent of carbon, nitrogen and oxygen in caffeine, c8h10n4o2.

Explanation:

Molecular mass of carbon  caffeine(), = 194 g/mol

Atomic mass of carbon = 12 g/mol

Atomic mass of hydrogen atom = 1 g/mol

Atomic mass of nitrogen atom = 1 g/mol

Atomic mass of oxygen  atom = 1 g/mol

Percentage of an element in a compound:

Percentage of carbon:

Percentage of hydrogen:

Percentage of nitrogen:

Percentage of oxygen :

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
