Suppose there are two known compounds containing the generic elements x and y. you have a 1.00-g sample of each compound. one sample contains 0.26 g of x and the other contains 0.35 g of x. identify plausible sets of formulas for these two compounds. check all that apply.

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".
