The empirical formula of a group of compounds is CHCl. The active ingredient in permethrin, a powerful insecticide, is a member of this group. The molar mass of the compound is 290.8 g/mol. How many atoms of carbon does a molecule of the compound contain

6 atoms of carbon.

Explanation:

Hello,

In this case, we can easily compute how many times the molar mass of the empirical formula is in the molecular formula by firstly computing it:

Then, we divide them:

Which is approximately 6, for that reason, we are going to find six atoms of carbon in the molecule.

Regards.
