5.20 kJ of heat is required to convert a 9.00 g sample of aldehyde from the liquid to gas phase. The heat that is
required to convert an 18.0 g sample of aldehyde from the
liquid to gas phase is required to convert 26.4 g sample of
benzene from the liquid to gas phase. What is the heat of
vaporization of benzene in J/g?
J/g

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".
