Dexamethasone is poorly water-soluble. its solubility could be improved by using a co-solvent, such as ethanol. to minimise the ethanol content in an oral formulation, optimal water/ethanol mixtures should be used. dexamethasone elixir usp contains 5.00% of ethanol. calculate the solubility parameter of the mixed solvent in this formulation.

how to solve this?

What happened in 2012 and how does it illustrate the importance of understanding the sun and how it works?

Joe shines white light into a bowl half full of water at an angle of incident of 27.5°. calculate the angle of refraction in the water given the indices of refraction for air and water are 1.00 and 1.36, respectively.

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.
