365. Calculate the degree of separation RS of alcohols from butanol and the mass fraction (%) of each component in the mixture (using the method of internal normalization), if a chromatographic curve with 4 peaks is obtained - methanol, ethanol, butanol, pentanol. The chromatographic characteristics of the peaks are presented in the table:
Alcohols h, mm a, mm f, mm
Methanol 72.3 3 64.7
Ethanol 126 3 78.5
Butanol 312 7 97.2
Pentanol 2961 10 123
