Unformatted text preview: Calculate the molality of concentrated HCl. 8. Calculate the vapor pressure of an aqueous solution of 30 C made from 1.00x10 2 g of sucrose (C 12 O 22 H 11 ) and 1.00x10 2 g of water. The vapor pressure of pure water at 30 C is 31.8mmHg. Answers: 1. Molarity: Easy to measure volume of solution, but volume changes with temperature. This means that molarity can also change. M= mols solute/ L of Solution Molality: Easy to measure stable concentrations of mass because it will not change, but more difficult to with solvents and solutions. m= mols solute/ mass of solvent (kg) 2. 0.638m 3. 8.92M 4. 13.88m 5. 13.8% 6. 2.33M 7. 15.7m 8. 30.2 mmHg...
