• cold

A solution of HCL contains 1 mole in 4 L of solution. What is the molarity of the solution?

• 4

• 0.25

• 5

• 3

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

• Supersaturated
• Saturated
• Unsaturated
• Undefined
