Calculate the amount of activated charcoal needed to make 1 mol of Alizarin Yellow R. Assume one molecule of Alizarin Yellow R has a contact area of 200 Å2 (2.0 x 10-18 m2) and 1 gram of activated charcoal has a surface area of 800 m2. Na = 6.02 x 1023 molecules/mol, Å = 10-10 m Options: 1.5 Kg 1.5 g 1.5 mg 0.0015 mg
