Question

What is the empirical and molecular formula for ibuprofen?

Answer 1

There is only one formula for ibuprofen...

Explanation:

That is `C_13H_18O_2`. This is because there are no more factors for all the three numbers and so the formula cannot be reduced.

So, the molecular and empirical formula of ibuprofen would be just `C_13H_18O_2`.
