A chemist makes 0.290 L of zinc oxalate (ZnC,°4) 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 determine the concentration of the working solution, we can use the formula:
M1V1 = M2V2
Where:
M1 = initial concentration of the stock solution = 0.0000680 M
V1 = initial volume of the stock solution = 0.160 L
M2 = concentration of the working solution
V2 = final volume of the working solution = 0.290 L
Plugging these values into the formula, we get:
(0.0000680 M)(0.160 L) = M2(0.290 L)
M2 = (0.0000680 M * 0.160 L) / 0.290 L
M2 = 0.0374 M
Therefore, the concentration of the chemist's working solution is 0.0374 M.
