Volume of water plus sample minus volume of water in graduated cylinder
The correct answer is the second statement. The solvent will have a higher boiling point. Adding a non-volatile solute to a pure solvent will increase the boiling point of the solvent. This solution exhibit colligative properties. Colligative properties depend on the amount of solute dissolved in a solvent. These set of properties do not depend on the type of species present.
7. a. I
8. c. 75 g/ml
9. b. .25g/cm3
10. b. the density decreases
1 atm = 760 mmHg
29.8 mmHg / 760 mmHg * 1atm = 0.039 atm
