WKST- Molarity Practice
Period/Teacher: ___________________________
Show work for each problem by: 1.) Writing the Equation 2.) Filling in variables 3.) Answering with sigfigs/labels.
1) What is the molarity of a 0.30 liter solution containing 0.50 moles of NaCl?
2) If a 0.075 liter solution contains 0.0877 moles of CuSO4, what is the molarity?
3) How many moles of NaCl are present in 600. mL a 1.55 M NaCl solution?
4) How many grams of H2SO4 are present in 1.63 liters of a 0.954 M solution?
5) How many liters of solution are needed to make a 1.66 M solution containing 2.11
moles of KMnO4?
6) What volume, in liters, of a 0.25 M solution can be made using 40.8 g of Ca(OH)2?
7) How many grams of CaCl2 will be needed to make 750 mL of a 0.100 M solution?
8) What is the molarity of a solution prepared by dissolving 40.3 g of NaOH in water to
make 280 mL of solution?
9) You are in charge of making all of the solutions your classmates need to do a lab. If there
are 6 lab groups and each group needs 250 mL of a 0.057 M solution of NaC2H3O3, what
mass of the sodium acetate will you need?
10) Write a brief procedure and explain how you would make 450 mL of a 0.250 M NaOH
solution. Remember, use steps to help organize your directions and grams/mL, not mol
and liters.
