How many moles are in 272g?

Answer 1

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.

Answer 2

To find the number of moles, divide the given mass (272g) by the molar mass of the substance. For example, if the substance is water (H2O), the molar mass is approximately 18g/mol. Dividing 272g by 18g/mol gives you approximately 15 moles.
