To calculate the concentration of the chemist's working solution, we will use the formula:
M1V1 = M2V2
Where:
M1 = molarity of the stock solution
V1 = volume of the stock solution
M2 = molarity of the working solution
V2 = volume of the working solution
Given:
M1 = 0.0000432 M
V1 = 0.270 L
V2 = 0.490 L
Plugging in the values:
(0.0000432 M)(0.270 L) = M2(0.490 L)
0.000011664 = M2(0.490)
M2 = 0.000011664 / 0.490
M2 = 0.0000238 M
Therefore, the concentration of the chemist's working solution is 0.0000238 M.
M1V1 = M2V2
Where:
M1 = molarity of the stock solution
V1 = volume of the stock solution
M2 = molarity of the working solution
V2 = volume of the working solution
Given:
M1 = 0.0000432 M
V1 = 0.270 L
V2 = 0.490 L
Plugging in the values:
(0.0000432 M)(0.270 L) = M2(0.490 L)
0.000011664 = M2(0.490)
M2 = 0.000011664 / 0.490
M2 = 0.0000238 M
Therefore, the concentration of the chemist's working solution is 0.0000238 M.
