A 500 mL sample containing the two molecules shown below. The sample has two DIRECT absorbance values – 0.310 at 275 nm (E=6000 cm-1) and 0.221 at 356 nm (E=9700 cm-1). How much anthracene is in the sample?
Are there any type of detergent/surfactant chemicals that would be good for removing dirt and grease from fabric that also would evaporate from the clothes within, say, 24 hours leaving no residue?
Is it possible to say water vapour and dew is same. I know that the water vapour is the gaseous phase of the water. But what is the dew. I just wonder how can I categorised it.Is it liquid or the gas phase of the water.
Figure below shows dew formed in grass. It seems as a liquid. But is it ac...

@Martin-マーチン Given that I've spent weeks trying to solve the same freaking problem over and over again in entirely different ways and I am coming up with squat, I'll take anything I can get.
@Martin-マーチン You see, we do {|c|c|} in array. If you do {|c@{something}c|, then instead of a line, the array's elements will be like XXX something YYY instead of XXX | YYY.

Can anyone explain to me that how solvent factor affect the wavelength and intensity of gold nanoparticle and silver nanoparticle in UV spectroscopy?
