A medication B is available as a concentrated paste (of unknown concentration – see later). 0.1406 g of the paste was made up to 100 mL with water. This “original” solution was diluted serially twice further, each time a hundred-fold (i.e. 1 mL to 100 mL). The final dilute solution was analyzed and found to contain 36.68 ng of B per mL. What was the concentration of the paste in terms of %B by weight of paste?

The total concentration of dissolved particles in blood is 0.30 M. An intravenous (IV) solution must be isotonic with blood, which means it must have the same concentration. (a) To relieve dehydration, a patient is given 190. mL/h of IV glucose (C6H12O6) for 2.0 h. What mass (g) of glucose did she receive? (b) If isotonic saline (NaCl) is used, what is the molarity of the solution? (c) If the patient is given 160. mL/h of IV saline for 3.0...

1) Suppose you made an intravenous solution, intended to be isoosmotic to red blood cells (i.e., 300 mOsm). You add 5 grams of NaCl to 800 ml of distilled water. Will this solution be isoosmotic to cells? if not, what will happen to the cells? (Will they take in water or lose water?) How would you make 500ml of a 5% NaCl solution? You dissolve 20 grams of glucose into water to give a solution whose final volume is exactly...
