Question

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

Answer 1

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.
