The number of moles of 20.0 mg caffeine ( C 8 H 10 N 4 O 2 ) is to be calculated. Concept introduction: The theory using which any substance’s quantity as its moles can be interpreted is addressed as mole concept.Molar mass value corresponding to the substance in addition to its mass should be known to evaluate its respective moles. Numerically, it is computed by using equation Moles = Given mass/Molar mass .
