11. A 239.4 mg sample of a drug designed to treat malaria was run through a series of reactions to convert all the nitrogen in the compound into N c The gas collected over water at 23.8°C and a pressure of 755,5 torr
had a volume of 18.66 L. The vapor pressure of water at this temperature is 22.11 torr. Calculate the percent
by mass of nitrogen in the sample

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

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".

i think it's letter a.

c) should be the answer.
