  1. Clicker #1 You add 300.0 mL of water to 300.0 mL of a 2.00 M sugar solution. How many of the following will change? I. total volume of the solution II. moles of solute in the solution III. mass of solute in the solution IV. concentration of the solution V. number of solute molecules in the solution A) 1 B) 2 C) 3 D) 4 E) 5

  2. Clicker #2 If 200. mL is removed from the original 10.0 M solution, what is the concentration of the remaining solution? A) 0.100 M B) 1.00 M C) 2.00 M D) 8.00 M E) 10.0 M

  3. Clicker #3 Do you predict that the concentration of the 4.00 M sugar solution will increase, decrease, or stay the same? A) increase B) decrease C) stay the same

  4. Clicker #4 Without using a calculator, which solution has the greater concentration? MM of NaOH = 39.99 g/mol MM of KCl = 74.55 g/mol A) NaOH B) KCl
