A stock solution of potassium nitrate, KNO3 has a concentration of 0.25 M. What volume of dilute potassium nitrate
(0.10 M) can be formed with 80.0 mL of the concentrated solution?
6. What volume of concentrated nitric acid, HNO3 (15.8 M) should be added to water to form 500.0 mL of a 3.0 M
nitric acid solution?
7. A sample of 7.0 mL of concentrated sulfuric acid, H2SO4 is used to make 250. mL of a 0.50 M sulfuric acid solution.
What was the initial concentration of the sulfuric acid?
Any help on one of these will be nicely appreciated tanks
