Question

A solution containing 20.00 g / L of B had an absorbance of 0.25 in a 2.00 cm cell at 690 nm. If 5.00 mL of this solution was diluted with 95mL, of water, what is the absorbance of the new solution at 690 nm?​

Answer 1

The absorbance of the new solution after dilution at 690 nm is approximately 0.0037.
