Editing Ammonium-Sulfate-Saturation-Table

'''Amounts of solid ammonium sulfate required to change the&nbsp;% saturation of 100 mL of solution'''<br> The table below is used to determine how much ammonium sulfate (in grams) must be added to100 mL of solution to change from any particular&nbsp;% saturation to any other&nbsp;% saturation. To use the table, start by finding the entry in the first column that gives the initial&nbsp;% saturation of your solution. (For example, this would be the first entry, 0%, before any ammonium sulfate has been added.) Then find the entry in the top row that shows the desired final&nbsp;% saturation of ammonium sulfate for the solution.&nbsp; The value at the intersection of that row and column is the amount of solid ammonium sulfate that must be added to 100 mL of solution to change from the initial to final&nbsp;% saturation. 

Example: I have 25 mL of a solution at 40% saturation that I would like to take to 80% saturation with ammonium sulfate. 

The initial concentration is 40% saturation, so in the first column I find the box called "40&nbsp;%." <br> The desired final concentration is 80% saturation, so in the top row I find the box called "80&nbsp;%." <br>The value at the intersection of this row and column is "26.3" so I would add 26.3 g to 100 mL. <br>Since I am using only 25 mL, I would add only a quarter as much, or 6.6 g.<br> Final Concentration (% saturation at 0 <sup>o</sup>C) of ammonium sulfate solution
