Interpretation:
Given the molar mass of caffeine, its molecular formula is whether
Concept Introduction:
Empirical formula of a compound represents the proportion of the elements in a compound irrespective of the numbers of atoms arranged in the molecule of the compound.
Name of compound based on its empirical formula is empirical name of the compound.
Molecular formula of a compound represents the number of atoms present in the molecule irrespective of the arrangement of those atoms and structure of the compound.
Molar mass of a substance can be calculated from its molecular formula by taking the sum of atomic masses of all the elements present in it.
Molar mass, number of moles and mass of a substance are related as,
