Question

Aqueous solution of absorbs 10%of the incident radiation in a path of 1cm length.Calculate the concentration of the solution which will absorb 90 %of the same incident radiation in the same path length

Answer 1

Answer:

The path length also affects absorbance. With a longer path length, the light has to travel through more solution, and can hit more molecules, and be absorbed. ... The pathlength is increasing. There are more molecules in the way of the light, so more light can be absorbed and less will be transmitted to your eye.

i hope this will help uh
