Molar Mass can be defined as the Mass of a sample of that compound divided by the amount of substance in that sample, measured in Moles. When the molecular mass of a solute is calculated from the Colligative properties of solution (In which that solute has been dissolved), are sometimes fo...
Molar Mass for Elements The mass in grams of one mole of substance is called molar mass. Each element has its own unique molar mass. For example, carbon’s molar mass is 12.011 g/mol, and magnesium’s molar mass is 24.3050 g/mol. To see why these elements have different molar masses...
