A 10ml sample of pure Orange Juice was diluted with 40ml of metaphosphoric acid solution. Then 10ml of diluted juice was titrated to an endpoint with 9.27ml of DCIP. A blank required .25ml of DCIP. A 1mg sample of pure ascorbic acid required 6.52ml(after blank correction) of DCIP. What is the concentration of ascorbic acid in the orange juice in mg/100ml?
