Retake Criteria for Unit 11 Solutions Assessment
All activities and the retake assessment must be completed
by Wednesday, April 22, 2015.
You MUST (not optional) make a NEW index card for the retake test,
focusing only on the sections that are being retaken.
Learning Target #1… Solutions Conceptual
You must…
1. meet with Mrs. Hatters and go over this section before retaking.
You can choose to either…
2. go to the following website and take the quiz.

When you have completed the quiz, print out your score. On the back of that paper, you
must “fix” any questions that you missed by writing out a true, complete statement.
3. Complete the new Conceptual worksheet (scroll down)

When you have completed the quiz, print out your score. On the back of that paper, you
must “fix” any questions that you missed by writing out a true, complete statement.
3. Complete both worksheets and get checked by Mrs. Hatters BEFORE the retake;
Solubility WS #1 AND Unit 11 Review (in class)
Learning Target #2… Solutions Calculations
You must do ALL of the following activities…

Solubility Graph
Learning Target #3… Calculations
You must meet with Mrs. Hatters and go over this section before retaking.
1. Sea water contains roughly 28.0 g of NaCl per liter. What is the molarity of sodium
chloride in sea water?
2. How many moles of Na2CO3 are in 10.0 mL of a 2.0 M solution?
3. What weight (in grams) of H2SO4 would be needed to make 750.0 mL of 2.00 M solution?
4. How many milliliters of 3.00 M NaCl are required to prepare 500. mL of a 0.450 M
solution?
5. What is the molarity of a 6000 mL solution if it has 130 grams of NaOH in it?
6. What is the volume, in Liters, for a 5M solution containing 450 g of CaCl2?
