Molality of C a ( N O 3 ) 2 and the total molality of the ions in the solution are to be determined. Concept introduction: Mole fraction: Amount of that component divided by the total amount of all of the components of the mixture ( n A + n B + n C + ... ) . Mole fraction of A (χ A )= n A n A + n B + n C + ... Weight percent: The mass of one component divided by the total mass of the mixture, multiplied by 100 % weight % A = Mass of A Mass of A + Mass of B + Mass of C + ... ×100% The number of moles of any substance can be determined using the equation Number of mole = Given mass of the substance Molar mass Molality (m): Molality is the number of moles of solute present in one kilogram of solvent. Molality (m) = Number of moles of solute 1kg of solvent Molarity (M): Molarity is number of moles of the solute present in the one liter of the solution. Molarity (M) = Number of moles of solute 1 liter of solution Density is calculated by the equation, Density = mass volume
