That was a wierd one..I think I wrote something like vitamin C is an antioxidant which reduces the risk of developing CVDs which are diseases of the heart and blood vessels

Hope that's right:biggrin: The rest of the exam was super easy. Though what did you write for the concentration of vitamin C in lemon juice (carton)? I left the calculation but wrote the answer because it was literally there on the next page in the bar chart

Ah...I knew they wrote in a confusing way. I'd actually left it till the last minute but they had shown the concentration for all types of juices in the bar chart on the next page so I just measured it from there...It was 0.6 mg/dm3

I just divided it...I don't remember exact numbers but I think it was 0.4 over 9. Something...It just said percentage of fresh over that of carton like juice so divided carton over fresh tomes 100 to get percentage. What did you get?
