ghout the semester you will be making solutions for your experiments. You may need to go ba general chemistry knowledge to remember concepts relating to grams, molarity and solute entages. INFORMATION SHEET A (see page 4) describes some of these important relationship will need several solutions for some of the experiments later in the semester that you will prepare ab. d below are the solutions you need to make and space to write your calculations. Please make s ave one of the TAs or the professor check your calculations before you make up the solutions. The of 3 of the solutions need to be adjusted - use INFORMATION SHEET B. Review how to use a ropipette before you begin - use INFORMATION SHEET C hen making solutions it is importantto properly label containers. e solution should be labeled to show the concentration of every lute, your initials (or name), your class/instructor's name, and the ate. 30 mL of 0.05M sodium succinate - make this solution in a 50mL conical tube and store for later use at 4°C. 1. | 1 |110 0,3 FS 0 3 4Explanation / Answer
Assuming mono Sodium Succinate(MSS) i.e. C4H5NaO4,
Molar mass of MSS MW = 140.07 g/gmol
Molarity required M = 0.05M
Volume required V = 30ml = 0.03lt
Number of moles of the compound required n = M*V = 0.05*0.03 = 0.0015 moles MSS
Therefore the mass in grams of the compound required = n*MW = 0.0015*140.07 = 0.21 g
Therefore the answer is 0.21 grams.
