5. The resistance of the aqueous extract of an ashed sample of cheese containing table salt in a cell with electrodes with an area of 2.54 cm2 and a distance between them of 0.65 cm is equal to 5.61 Ohm. Determine the percentage of sodium chloride in cheese if the molar electrical conductivity of the extract solution is 79.7*10-4 Ohm-1*m2*mol-1, and the density of the solution is 1.01 g/cm3.
