Molarity: Describe how many liters of water and how many grams of the following chemicals you need to add to make the following solutions
(See p. 412-415 in chapter 13 for help with these molarity problems)
1. Make 6.00L of a 5.60M solution of Copper (II) Sulfate
2. Make 1.50L of a 1.25 x 103M solution of Aluminum Nitrate
3. Make 8.52L of a 1.00M solution of Sodium Hydroxide
4. Make 300.0mL of a 2.58M solution of Magnesium Chloride
5. Make 800.0mL of a 2.87 x10-5M solution of Calcium Phosphate
6. Make 1000.0mL of a 5.97 x 10-3M solution of Sodium Chloride
7. Make 1.00L of a 4.56 x 10-3M solution of Copper (II) Sulfate
8. Make 6.00L of a 3.67 x 10-3M solution of Barium Hydroxide
9. Make 80.0 mL of a 2.45 x 10-3M solution of Aluminum Hydroxide
10. Make 15.0 mL of a 3.56 x 10-3M solution of Sodium Chloride
Molarity: Making molarities from stock solutions (sample problem 13-2 on p. 414 will
help somewhat with these problems. DRAW
THEM FIRST, IT HELPS!)
1. Make 1.00 L of a 6.00 M solution of HCl from a stock solution of 12 M
2. Make 4.00 L of a 6.00 M solution of HCl from a stock solution of 15 M
3. Make 400. mL of a 5.00 M solution of HCl from a stock solution of 12 M
4. Make 600. mL of a 4.90 M solution of HCl from a stock solution of 8 M
5. Make 350. mL of a 8.00 M solution of HCl from a stock solution of 12 M
6. Make 3000. mL of a 5.05 M solution of NH3 from a stock solution of 10 M
