Concept explainers
Interpretation:
Molecular formula of the eugenol has to be determined.
Concept Introduction:
Mole is S.I. unit. The number of moles is calculated as ratio of mass of compound to molar mass of compound.
The expression to relate number of moles, mass and molar mass of compound is as follows:
Empirical formula represents simplest positive integer ratio of atoms in the compound. It only gives proportions of elements in compound. Molecular formula consists of
