The concentration of dye in Solution A is 20.926 M. A serial dilution is performed to make Solutions B and C. In the first dilution, 7 mL of Solution A is diluted with 12 mL water to make Solution B. Then, 2 mL of Solution B is then diluted with 1 mL of water to make Solution C. What is the concentration of dye in Solution C? Provide your response to three significant figures in units of molarity.

1. A series of dilute NaCl solutions are prepared starting with an initial stock solution of 0.100 M NaCl. Solution A is prepared by pipeting 10 mL of the stock solution into a 250-mL volumetric flask and diluting to volume. Solution B is prepared by pipeting 25 mL of solution A into a 100-mL volumetric flask and diluting to volume. Solution C is prepared by pipeting 20 mL of solution B into a 500-mL volumetric flask and diluting to volume....

The concentration of a solution after dilution can be found
by:
where M1 is the concentrated solution (in
this lab, 0.400 M), and V1 is the volume of the
concentrated solution placed in the test tube. The
V2 is the total volume of
concentrated solution plus water added, and M2
is the concentration of the solution after diluting.
Tube 1 has 2.00 mL of the 0.400 M Ni2+ solution and
8.00 mL of water added. What is the concentration of...
