54. Solving a chemistry problem

The specific electrical conductivity of a 5% solution of Mg(NO3)2 at 18°C is 4.38 S/m, and its density is 1.038 g/cm3. Calculate the equivalent electrical conductivity of the solution and the apparent degree of dissociation of the salt in the solution. The mobility of Mg+2 and NO3- ions at 18°C is 44.6 and 62.6 Ohm1 cm2 mol1.
