The density of the solution is 1.21 g/ml and the density of the water is 1.0g/ml. A student taken 10.0 ml of this solution and dilutes it with water to 250 ml (3 SF). A solution is prepared by dissolving the 3.0 g ion (II) chloride (MW = 126.8 g/mol) with 75.0 ml of water. Determine the molar concentration of chloride ion in the diluted solution?
