From the Paper:

"The surface tension of deionized water and eight solution of n-butanol were determined using the capillary-rise method. The radius of the capillary was determined to be 3.59 x 10-2 + 0.15 cm. The value of the radius of the capillary allowed for the determination of the surface tensions of the eight n-butanol solutions. The surface tensions were then plotted versus the natural logarithm of the concentrations of the n-butanol solutions. The slope of the graph was then used to determine the amount of n-butanol adsorbed. This value was calculated to be 3.52 x 10-10 + 0.71 mol/cm2. This value was converted into 2.12 x 1014 + 0.71 molecules/cm2. The effective cross section area of one molecule of n-butanol was determined to be 4.72 x 10-15 + 0.71 cm2. The value of Avogrado's number was calculated using the value of n2/A and the molar volume of n-butanol. Avogrado's number was determined to be 2.74 x 1024 + 0.71."
