First find the volume of pure alcohol in each solution and thereby the total volume. Divide this by the total volume, assuming no contraction, provides the concentration of solution. http://www.boomer.org/c/snips/tut702.m4v Sun, 17 Sep 2006 21:48:14 -0500 Higher Education no 00:01:44 pharmacy calculations mathematics David and Aaron Bourne What is the concentration after dilution The concentration after dilution can be calculated using an inverse proportion. This can also be calculated using a conservation of amount. Concentration before dilution times the original volume is the same as the concentration after dilution times the new volume. http://www.boomer.org/c/snips/tut701.m4v Mon, 04 Sep 2006 16:28:45 -0500 Higher Education no 00:01:45 pharmacy calculations mathematics David and Aaron Bourne Determine how much sodium chloride is required using freezing point depression data Isotonic solutions freeze at -0.52 degree centigrade.
