Solutions Review 1

What is the molar concentration of a 100 mL aqueous solution that contains 1.00 g KCl?

• 1.34 M KCl
• 0.134 M KCl
• 0.0134 M KCl
• 0.00134 M KCl

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

If the temperature stays the same, the solubility of gases in liquids 

• increases with increasing pressure
• cannot reach equilibrium
• decreases with increasing pressure
• does not depend on pressure

What is the molality of an aqueous NaOH solution made with 5.00 kg of water and 3.6 mol of NaOH?

• 3.6 m NaOH
• 1.4 m NaOH
• 0.72 m NaOH
• 0.090 m NaOH

What mass of NaCl is needed to make a 1.5 m solution using 300 g of solvent?

• 26.3 g NaCl
• 11.7 g NaCl
• 1.50 g NaCl
• 0.0877 g NaCl

A 2 m solution contains

• 2 mol of solute dissolved in 1 L of solvent
• 1 mol of solute dissolved in 2 L of solvent
• 2 mol of solute dissolved in 1 mol of solvent
• 2 mol of solute dissolved in 1 kg of solvent

Seawater contains sodium chloride and other dissolved salts. Identify the term that correctly describes those dissolved salts.

• mixtures
• solvent
• solute
• element

What is a solution that has the maximum amount of solute dissolved at a specific temperature and pressure?

• Supersaturated
• Saturated
• Unsaturated
• Undefined

What is a solution called where more amount of solute  CAN BE dissolved at a specific temperature and pressure?

• Supersaturated
• Saturated
• Unsaturated
• Undefined

When the solution is holding more solute than its maximum (by raising the temperature saturating the solution and then lowering the temperature) it is said to be

• Supersaturated
• Saturated
• Unsaturated
• Undefined
