OK........but that will depend on the concentration you stated in part(d) for ethanedioic acid.
I just finished it now, but I do't have a scanner, so won't be able to upload it right away.
Am sorry I need to rush for now.........i'll be back later to elaborate. Same for your number in p2 Nov 07
Hope you don't mind :)
