To make a saturated solution with any certain concentration, you simply need to find out the temperature at which saturation occurs for that concentration.
Saturation for sugar, assuming you mean sucrose, at 0.6 molL-1 is below the freezing point of water (even at 0oC, it has a solubility of around 5.25molL-1); therefore, creating a saturated solution at this point is impossible.
>.actually. 2.4 moles
To find the total number of moles, multiply the molarity times the number of liters desired. For four liters of a .6M solution, there are 2.4 moles of sugar required.
0.6 x 4 = 2.4 Answer: 2.4 moles
2.4 moles
