I explained this below along with an implied suggestion that you clarify the question. By the way note the correct spelling of stoichiometry.
I don't know what you want with this. If it's a problem you want it to be worked correctly. If it's a synthesis you want to be able to control the cost. If it's a product you want a certain yield. If you can expand perhaps I'll know where you're going w...
Scroll to the picture. The quality is not very good but you can see the North American Plate (Okla is on this plate) and it also shows the adjacent plates. http://boingboing.net/2010/10/14/earthquakes-in-oklah.html
5 cm/yr x 1000 yrs = ?cm
8850 m = 885000 cm 2 cm/yr x #yrs = 885000 Solve for #yrs.
density? temperature? are you using pure or denatured alcohol? purity of alcohol? other?
I have no idea but I'd like to know when you find out. If you want to know the mass of the ethanol you won't get it this way. Perhaps if you explained how this question was generated (what experiment/subject/procedure) I may be able to get a better handle on it.
Use dolomite for maximum magnesia.
Let x = grams in organic layer, then 2-x = grams in water layer. Kd = 20 Kd = g/mL in organic layer/g/mL in aq layer. Then organic layer = xgrams/13.9 mL aq layer = (2-x)grams/15 mL.
I can show you how. dG = -RT*lnK dG = -4.65 kJ/mol = 4650 J/mol substitute in the above and solve for K. Then ............A + B ==> C I..........0.3..0.4...0 C..........-x...-x....x E........0.3-x...4-x..x Substitute the E line into the Keq expression (use K from the first ...
