If 2.00 mL of a solution is diluted to 20.0 mL and the absorbance of the 20.0 mL solution is found to be 0.15, what is the molarity of the 2.00 mL solution?
Added by Grace K.
Step 1
This means that if we dilute a solution, its absorbance will decrease proportionally. In this case, the 2.00 mL solution was diluted to 20.0 mL, which is a dilution factor of 10 (20.0 mL / 2.00 mL = 10). Since the absorbance of the diluted solution is 0.15, the Show more…
