The percentage c by mass in the above unidentified substance is 54.5%. it may also contain h and/or o, but no other element. what is the molecular formula of the substance? (in typing this formula use the convention of c first, h second and o last. for example, c6h8o2 would be c6h8o2.)

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
