Adipic acid, C6H10O4, is a raw material for the making of nylon and it can be prepared in the laboratory by the following reaction between cyclohexene, C6H10, and sodium dichromate, Na2Cr2O7 in sulphuric acid.
3 C6H10 + 4 Na2Cr2O7 + 16 H2SO4 >
3 C6H10O4 + 4 Cr2(SO4)3 + 4Na2SO4 + 16 H2O

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.
