I got 6% for the concentration of ethanoic acid which from reading answers online seems to be wrong,will I get 0 even if my calculations were the correct method?
Soniclouise — 21/06/16
no they will give you you marks for the method maybe obly 3 but its something

I messed up in a place where I wrote 0.8 instead of 0.08. This meant my other answers further down were also affected by this. How many marks will I lose for this? Will I only be marked down for the initial slip or will marks be taken away from the other answers as well?
