(Read the paragraph and answer the questions follows) The maximum amount of solute that can be dissolved in a fix amount of solvent at a fix temperature is called solubility. On the basis of amount of solute dissolved in solution, there are three types of solutions- i. supersaturated, ii. saturated and iii. saturated solutions. Supersaturated solutions contains more amount of solute than solubility. Saturated solutions has amount of solute equal to the solubility but unsaturated solutions has less than solubility. Supersaturated solutions are unstable and convert into saturated solutions by precipitation. Unsaturated solutions can be converted into saturated by evaporation of solvent. A). If solubility of a solute 'X' in water is 29 g/Litre, 2.9 g/Litre solution of solute 'X' in water is called- * 2 points Saturated Supersaturated unsaturated semisaturated 8) B). If solubility of another solute 'Y' in water is 2.9 g/Litre, saturated solution of it should contain g solute in mL solution. * 2 points 29, 50,000 19, 1000 1.45, 500 2.9, 50,00 This is a required question 8) C). 20 g solute is dissolved in 50 g of solution. Calculate the mass % of solution. * 2 points 20% 50% 40% 25%
