A solution is prepared by mixing 25.0 mL of 0.100 M aqueous with 50.0 mL of 0.0200 M aqueous . Calculate the concentration of in this solution.
What does not change when a solution of sodium chloride is diluted from 1.0 L to 1.8 L?
A stock solution of sodium acetate is 1.0 M. To make solution A, 2.00 mL of the stock solution is transferred and diluted to a total volume of 100 mL. Solution B is made by transferring 5.0 mL of solution A and diluting it to a total volume of 250 mL. Solution C is made by transferring 1.0 mL of solution B and diluting it to a total volume of 25 mL. What is the concentration of solution C?
