Problem- The resolution for two compounds in a chromatogram was measured to be R = 0.928. The retention times for each compounds compound are

tR,A = 22.137 min

tR,B = 22.554 min

The dead time for the run was tM = 2.945 min. Determine the average number of theoretical plates in the column for these compounds.

I desire help for above question. Illustrate each step for the above problem.
