CONCENTRATION of a SOLUTION || Mass per cent || Mole fraction || Molarity || Molality || in HINDI

In this Chemistry video in Hindi for class 11 we explained the meaning of the concentration of a solution and four ways of measuring it, namely, mass per cent, mole fraction, molarity and molality. We discussed on the formula for mass per cent, mole fraction, molarity and molality. Mass per cent or weight per cent is the percentage in mass of solute in the solution. Mole fractionis the ratio of number of moles of a particular component to the total number of moles of the solution. Molarity is defined as the number of moles of the solute in 1 litre of the solution. Molality is defined as the number of moles of solute present in 1 kg of solvent. ★★★★★★★★★★★★★★★★ Click to visit the homepage of our channel :    / @edupoint.physics   EduPoint by Arijit Daripa
