A mixture of CO2 and N2 is in a container at 25oC, with each species having a partial pressure of 1 bar. Calculate the molar concentration in kmol/m3, the mass density in kg/m3, the mole fraction, and the mass fraction of each species. Ans: Let A = CO2, B = N2. CA = CB = 4.03(10-2 kmol/m3 (A = 1.775 kg/m3, (B = 1.13 kg/m3

Molar conductivity is the conducting power of cell the ions produced by one mol of an electrolyte. It is given by = Variation of and with concentration. Conductivity decreases with dilution. Because the number of ions per unit volume that carry the current in a solution decreases. Molar conductivity increases with decrease in concentration.
