Science > Chemistry > Solutions and Their Colligative Properties > Numerical Problems on Molarity In this article, we shall study numerical problems to calculate the molarity of a given solution. Example – 01: A solution of NaOH (molar mass 40 g mol-1) was prepared by dissolving 1.6 g of NaOH in 500 cm3 of water. […]

Science > Chemistry > Solutions and Their Colligative Properties > Concentration of Solution The concentration of a solution is the measure of the composition of a solution. For a given solution, the amount of solute dissolved in a unit volume of solution (or a unit volume of solvent) is called the concentration of the solution. […]

Science > Chemistry > Solutions and Their Colligative Properties > Numerical Problems on Mole Fraction In this article, we shall study to solve problems to calculate mole fraction of solute and solvent. Example – 01: 23 g of ethyl alcohol (molar mass 46 g mol-1) is dissolved in 54 g of water (molar mass 18 […]

Science > Chemistry > Solutions and Their Colligative Properties > Percentage Composition In this article, we shall learn to calculate percentages by mass and percentage by volume of a solution. Problems on Percentage by Mass Example – 01: 6 g of urea was dissolved in 500 g of water. Calculate the percentage by mass of […]
