Tyrosine contains 11 hydrogen atoms, 9 carbon atoms, 3 oxygen atoms, and 1 nitrogen atom. what is the chemical formula for tyrosine?

Chemical formula of compound describes and shows the number of atoms of each element that are present in a compound.

As in tyrosine number of atoms are:

hydrogen = H = 11

carbon = C = 9

oxygen = O = 3

nitrogen = N = 1

So the chemical formula will be:

C₉H₁₁NO₃

In writing chemical formula of organic compound, we write carbon first then hydrogen and then the other atoms.
