The maximum number of moles of radiations of Paschen series when 6 moles of excitedHydrogen atoms makes transition to Groundstate from 6th Bohr's Orbit.​

Answer»

When the excited electron of an H atom in n = 6 drops to the ground STATE, the following TRANSITIONS are possible: The number of spectral lines: 2n(n−1)​ where n=6Hence the total number of spectral line will be: 26×5​ =15Explanation:
