3. A solution contains 10 g of KNO3 per 100 g of water at 30˚C. Is the solution unsaturated, saturated or supersaturated?

4. An 8 oz bottle of Dr. Pepper made with imperial cane sugar (C12H22O11) contains 27 g of sugar in 236.6 mL of water.  What is the molarity of the solution with respect to cane sugar?  

5. Calculate the mass of NaCl in a 55 mL sample of a 3.5 M saline solution.  

6. What volume of water should be added to 2.6 g of KCl to make a 4 M solution?

Answer 1

a o ung of nau per 100g of H₂O at 100°c is dissolze 1 compeletely. So it is unsaturated solution. © A 4* 4 5") { ки рил 1») Н,0 d is ' - at that temperature only 35g of ku is dissolvet I left 15g of k U is undissolved, so it is satursted son . 1080 kno, piring tho at 30°c - all the knon dissolve in 100 g tho , so it ho unsaturated orlution. 0 molar mass of came sugar / suerone (C2H₂ 20:1) = 342.09.
