Concept explainers
Interpretation:
The information which is needed for the determination of molar mass of DEET should be identified.
Concept introduction:
A formula that represents a certain combination of elements present in a molecule is known as a molecular formula. In the molecular formula, the simpler number of every atom is present in a molecule.

Explanation of Solution
On the basis of molecular formula, first, identify the types of
To find the molar mass of the compound, multiply the molecular weight of the atom by the corresponding subscript number.
Now, for calculating the molar mass of DEET, first, one should know the molecular formula of DEET. From the molecular formula of DEET, types and number of atoms are identified.
Thus, the molecular formula of DEET should have known, for calculating the molar mass of DEET.
