Answer to Question #265517 in Physical Chemistry for Goje007
A solution contains 20.0g of NaCl in 750ml distilled water is found to have an absorbance of 2:52 at 520nm when the path length is 1cm. Calculate the molar absorptivity with units.
Molar mass of NaCl= 58.44
20/58.44= 0.342
750/1000= 0.75
Molarity= 0.342/0.75= 0.456mol/L
0.456×520= 237.28
