👉 Molarities are a measure of the amount of substance in a given volume or mass. In chemistry, they are often used to compare the properties of different substances based on their molecular weight and composition. The formula for calculating molarities is: molarity = moles (mass) / volume For example, if you have 10 grams of a substance with a molecular weight of 28 g/mol, then its molar mass would be 28. If you have
