Gram Molecular Weight of Cl 2 (one mole)= 35.5 x 2 = 71 g. 71 g of Cl 2 at S.T.P occupies 22.4 litres ..

Solubility: Is defined as the concentration of a saturated solution of a solute in a particular solvent at a particular temperature. Solubility is a specific maximum concentration. Solubility of sparingly soluble salts: 1) The weight of sparingly soluble salt in grams present in ..

Since reactions in solutions are by far the most common, we turn now to chemical calculations involving solutions. There are number of ways of expressing the amount of a substance in a given volume of a solution : normality as an unit in acid-base titrations and number of moles in redox titration..
