Ineed , i cannot figure this question !

The answer to your question is: 207.24 g

Explanation:

Average atomic mass of Lead = ( 0.014 x 204) + (0.241 x 206) + (0.221 x 207)

                                                     ( 0.524 x 208)

                                                  = 2.856 + 49.646 + 45.747 + 108.992

                                                  = 207.24 g

u i forgot the answer?

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".
