A chemist makes 0.290 L of zinc oxalate (ZnC3O4) working solution by adding distilled water to 0.160 L of a 0.0000680 M stock solution of zinc oxalate in water
Calculate the concentration of the chemist's working solution. Be sure your answer has the correct number of significant digits.
To find the concentration of the working solution, we can use the formula:
CiVi = CfVf
Where Ci and Vi are the initial concentration and volume of the stock solution, Cf is the final concentration of the working solution, and Vf is the final volume of the working solution.
Given:
Ci = 0.0000680 M
Vi = 0.160 L
Vf = 0.290 L
Substitute the values into the formula:
(0.0000680 M)(0.160 L) = Cf(0.290 L)
0.00001088 = 0.290Cf
Cf = 0.0000376 M
Therefore, the concentration of the chemist's working solution is 0.0000376 M.
