124. Solving a chemistry problem

521. When calibrating a conductometric cell, it was found that a KCl solution with a specific electrical conductivity of 0.14088 S/m has an electrical resistance of 654 ohms. In the same cell, a 0.100 mol/l NH4OH solution has a resistance of 2524 ohms. Calculate the cell constant and the molar conductivity of the NH4OH solution. Knowing the limiting molar conductivities of the ions NH4 and OH- 0.007355 and 0.01983 cm*m2*mol-1, respectively, calculate the degree of dissociation and the dissociation constant of NH4OH.
