Solve the following problems:
1. The solution made by dissolving 0.10 mol of KNO3 into 0.2 kg of H2O would be 0.50 molal in KNO3
2. Determine the molality of a solution prepared by dissolving 75.0g Ba(NO3)2 (s) with 0.28700 mole in to 0.37400 kg of water.
3. A 4 g sugar cube (Sucrose: C12H22O11) with a mole of 0.0117 mol is dissolved in a 0.35 L teacup of water. What is the molality of the sugar solution?
