Question

What is the Empirical formula for C₈H₈O_3?

Answer 1

molecular formula = C₈H₈O₃

molecular mass = 152.15 g/mol

Emperical formula : emperical formula giving the proportions of elements present in the molecule. not actual numbers or arrangement of atoms.

C            H            O

8              8             3   

here smallest whole number is 3 . 8 is not a common factor of 3 . so

Molecular formula = Emperical formula

Emperical formula = C8H8O3
