21-06-2016· From the above formula it can be seen that both the solids (zinc oxide and yellow soft paraffin) are expressed as grams and the liquid paraffin is expressed as millilitres (a volume). For all of these ingredients, 1 g does not occupy the volume of 1 mL (or vice versa), and so it is not possible to add volumes of millilitres to quantities in grams to obtain the answer.
