2) Identify seven different types of solutions according to physical state. Then explain how
they can be divided into three main categories.
3) List three methods of measuring the concentration of a solution. Write and explain the
equation used for each method.
4) What factors affect the rate at which a solute dissolves in a solvent?
5) What factors affect the solubility of a specific substance?
6) What is a colligative property? Describe four colligative proerties of solutions.
7) What is the molarity of a 0.50 L solution containing 9.0 g NaCl in water?
8) Chlorine is often added to water in swimming pools and to drinking water to keep clear
and free of living organisms. What is the molality of a solution made up of 16.1 g of
chlorine in 5000. g of water?
9) Vinegar is a solution of acetic acid. What is the molarity of the solution produced when
125 g of acetic acid is dissolved in sufficient water to prepare 1.50 L of solution?
(Hint: Acetic acid has 2 carbon atoms, 4 hydrogen atoms, and 2 oxygen atoms)
10) How many grams of bromine are needed to prepare 0.500 L of a 0.100 M solution
of bromine in water?
11) What is the molality of a solution containing 125 g of iodine and 750. g of carbon
tetrachloride?
12) A gas mixture contains 50.4 g of dinitrogen monoxide and 65.2 g of oxygen gas. What
is the mole fraction of dinitrogen monoxide?
13) How many grams of sucrose would have to be added to 0.500 kg of water to elevate
the boiling point by 5.0 degrees Celsius?
