In the following questions, "concentrated" refers to the concentration of the most common commercial regent as listed in the table of Concentrated REagents inside the back cover of the textbook.
1. An ammonia solution is made by diluting 150 ml of concentrated commercial
reagent until the final volume reaches 1000 mL. What is the final molar
concentration?
2. What volume of a 500 ppm reagent solution is requried to prepare
2.5 L solution with a 100 ppm concentration?
3. A 500 m L bottle of concentrated acetic acid is diluted to make a
5.0% solution. Find the colume of diluted solution that is prepared.
4. In a chemical analysis, a 25.0 mL sample was diluted to 500.0 m L
and analysed. If the diluted solution had a moalr concentration of 0.108
mol/L, what was the molar concentration of the orginal sample?
5. If a 355 m L can of soda pop is diluted to a final colume of 1.00
L, what can be said quantitatively about the concentration of the diluted
solution as compared with the orginal solution?
