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.
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.
