A3.17 m solution of cacl2 in water has a density of 1.24 g/ml. what is the molarity?

Given the molality of CaCl2 solution = 3.17 m

That means 3.17 mol are present per 1 kg water.

Mass of =

Mass of solution = Mass of solvent + Mass of Solute = 1000 g + 351.8 g = 1351.8 g solution.

Density of solution = 1.24 g/mL

Volume of the solution =

Molarity is the moles of solute per L of the solution

Calculating molarity of the solution:

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
