EXERCISES, LESSON 8
INSTRUCTIONS: Answer the following exercises by writing the answer in the space
provided at the end of the question.
After you have completed all the exercises, turn to "Solutions to Exercises" at the
end of the lesson and check your answers. For each exercise answered incorrectly,
reread the material referenced with the solution.
1. How many mL of phosphoric acid (H3PO4), 1.69 S.G., 85.0 would be needed to
make 500 mL of a 1.00 Eq/L H3PO4 solution?
2. A commercial HCl solution has a S.G. of 1.15 and 33.0
Find the mol/L concentration of the solution.
How much concentrated solution would be required to make 1.00 L of a
2.00 Eq/L solution?
3. How much NH4OH with a specific gravity of 0.960 and an assay of 26.0 percent is
required to make 750 mL of 4.00 Eq/L ammonium hydroxide solution?
4. What is the g/dL concentration of the concentrated solution in exercise 3?
