Calculate the amount of charcoal required to effectively decolorizethe salicylic acid.
Information given to me;
- crude salicylic acid= 1g, containing 0.2% Alizarin Yellow R
- (not sure if this is important, but we add 25ml of water)
- activated 1g of charcoal has an area of 800m2
- area of contact of Ali Yellow R is approximately 200A2 (A=1x10-10m)
- alizarin yellow R (M.W. of 287.23, formula isC13H9N3O5)

Question (has 4 parts)
a) Calculate weight of Alzarin Yellow R in the 1g sample ofsalicylic acid.
b) Convert this to the number of moles, and thence the # ofmolecules.
c) Calculate the total area occupied by these molecules.
d) Calculate the weight of activated charcoal needed that wouldprovide this area.
