Mass of dcpip
WebAs each cm3 of 0.1% DCPIP (MWt 290.08) solution is equivalent to 6.071×10-4 g ascorbic acid (MWt 176.12). Therefore 1 cm 3 of extract must have contained 9.107×10-4 g of ascorbic acid. This means the original 50 cm 3 extract contained 0.0455 g and this came from 10 g of fruit. So you can work out that each gram contained 0.00455 g ascorbic acid.
