Exercise #2:
We have 4 stock solutions. We want to dilute these stock solutions to make 4 new solutions.
How much water do we have to add to the stock solution to make the desired concentration? Stock solutions Desired Solutions Volume of the desired (new) solution Volume of water added to the stock solution 1 liter of Urea 1 M 0.3 M Urea 500 ml of Glycerol 0.5 M 0.3 M Glycerol 10 ml Glucose 0.3 M 0.2 M Glucose 2 liters of NaCl 2 M 0.15 M of NaCl Click here to check your answers-->
