It depends on what the subtance is, i.e. whether there is 272g of copper, sodium chloride, lithium hydroxide or what. The way to calculate the amount of a subtance in moles is to divide the mass of the substance (in grams) by the Atomic Mass, molecular mass or formula mass of the element, molecular compound or ionic compound respectively, as the case may be.
