What volume of 2.50 x 10-4 M CV+ solution should be diluted to 10.0 mL to prepare a 7.50 x 10-5 M CV+ solution
The dilution formula is
mL1 x M1 = mL2 x M2.
the
To find the volume of the 2.50 x 10-4 M CV+ solution that should be diluted, we can use the dilution formula:
C1V1 = C2V2
Where:
C1 = initial concentration of the solution
V1 = initial volume of the solution
C2 = final concentration of the solution
V2 = final volume of the solution
Given:
C1 = 2.50 x 10-4 M
V1 = unknown (let's call it x)
C2 = 7.50 x 10-5 M
V2 = 10.0 mL = 10.0 x 10-3 L
Plugging in these values into the dilution formula, we get:
(2.50 x 10-4 M)(x) = (7.50 x 10-5 M)(10.0 x 10-3 L)
Now, we can solve for x:
2.50 x 10-4 M *x = 7.50 x 10-5 M * 10.0 x 10-3 L
x = (7.50 x 10-5 M * 10.0 x 10-3 L) / (2.50 x 10-4 M)
x = 3.00 x 10-5 L
To convert this volume into milliliters, we multiply by 1000:
x = (3.00 x 10-5 L) * 1000
x = 3.00 x 10-2 mL
Therefore, approximately 3.00 x 10-2 mL or 0.030 mL of the 2.50 x 10-4 M CV+ solution should be diluted to 10.0 mL in order to prepare a 7.50 x 10-5 M CV+ solution.
