solutions mole dilution colligative

A dissolved solute that does not form ions is:

• a nonelectrolyte
• a weak electrolyte
• a strong electrolyte
• insoluble

To determine the molarity of an HCl solution, you need to know the number of: 

• g of HCl in 100000 g of solution
• moles of HCl dissolved in the total moles of solution
• moles of HCl in 1 L of solution
• moles of HCl dissolved in 1 kg of solvent

Colligative properties of solutions are those properties that depend on

• the amount of solute only

• the identity of solute only

• both the identity and the amount of solute

The freezing point of a solution is ___________ that of a pure solvent

• more than

• less than

• equal to

The boiling point of a solution is ___________ that of a pure solvent

• more than

• less than

• equal to

The amount of solute actually dissolved in a given amount of solvent.

• dilution
• concentration
• saturated solution
• supersaturated mixture

__________ are made up of solutes and solvents.

• Solutions
• Suspension
• Colloid

True or False? The higher the concentration of a solution the less solutes it has in it.

• True
• False

Calculate the molarity of the following solution:  1.0 mole of KCl in 750.0 mL of solution.

• 0.750 M
• 99 M
• 1.3 M
• 2.0 M

Molarity is measured in

• moles per kg
• mols per L
• moles per kJ
• moles per mL
