You are washing glassware in a lab. The solution your 1 L beaker contains 5 mol/L NaOH in water. It is known that 1% of the mixture adheres to the walls of the beaker when the beaker is drained. Thus, if you drain the beaker, 0.01 L of the original contents of the beaker remains in the beaker. The beaker must be filled with 1 L of pure water between each rinse. The beaker is then stirred very well. What is the composition of the contents of the beaker, in mol/L, if it is rinsed once? How many rinses does it take to get the contents of the beaker to below 0.00005 mol/L?

The explanation is given below-
