L51.Potassium chloride has solubility 43.0 g/ 100 g water at 50oC. Will a mixture of potassium chloride (110.0 g) and water (250 g) form a saturated solution at 50oC? If so, then what mass of potassium chloride will remain undissolved?2.Calculate the concentration, % m/m, of a solution containing 26.0 g solute and 726.0 g water.3.Calculate the molarity of a 10 % m/v solution of calcium nitrite.
