Solubility of ammonium chloride at 293 kelvin is 37 gram what mass of Ammonium Chloride would be needed to make a saturated solution in 10 gram of water at 293 Kelvin

Answer»

3.7 gram of Ammonium Chloride would be needed to make a saturated solution in 10 gram of waterExplanation:GivenSolubility of Ammonium Chloride (NH₄Cl) at 293 K is 37 gram/100 mLi.e. 37 gram of NH₄Cl is SOLUBLE in 100 mL of wateror, 37 gram of NH₄Cl is soluble in 100 gram of WATER  (∵ DENSITY of water = 1g/ml)∵ In 100 gram of water AMOUNT of NH₄Cl soluble = 37 gram∴ In 1 gram of water, amount of NH₄Cl soluble = 37/100 gram                                                                               = 0.37 gram∴ In 10 gram of water, amount of NH₄Cl soluble = 0.37 × 10 = 3.7 gramTherefore, 3.7 gram of Ammonium Chloride would be needed to make a saturated solution in 10 gram of water
