Calculate the final concentrations of the following aqueous solutions after each has been diluted to a final volume of 25.0 mL.

Question

1.00 mL of 0.452 M Na+

2.00 mL of 3.40 mM LiCl

5.00 mL of 5.70 mM Zn2+

Answer 1

The dilution formula works all of them.
mL1 x M1 = mL2 x M2. For example:
1 mL x 0.452M = 25 mL x ?M. Solve for ?M
