from:Chamberlin, Amanda


What do you need to know in order to determine the concentration of a solution?

Define the term molarity.

How many moles of sucrose are in one liter of soda pop with a molarity of 0.75M ? (C12H22O11 – sucrose).

What is the molarity of a 100 mL solution with 0.10 moles of potassium chloride (KCl) dissolved in it?

Which is more concentrated: a 1.0 L solution with 10 moles sucrose (C12H22O11) or a 1.0 L solution with 10 moles glucose (C6H12O6)?

Which of the following solutions has more moles?
1.0 L of 2.5 M NaCl
500 mL of 2.5 M NaCl
100 mL of 1.0 M NaCl
1.0 L of 5.0 M NaCl
