What volume of 25% solution is needed to make 500mL of a 10% diluted solution?
Can't you use the dilution formula of
mL x % = mL x %
mL x 25 = 500 x 10
Solve for mL.
200 ml
200mL
To calculate the volume of the 25% solution needed to make a 500mL 10% diluted solution, you can use the concept of dilution formula. The dilution formula can be expressed as:
C1V1 = C2V2
Where:
C1 = initial concentration of the solution (25%)
V1 = initial volume of the solution (unknown)
C2 = final concentration of the solution (10%)
V2 = final volume of the solution (500mL)
Substituting the known values into the equation, we get:
(25%)(V1) = (10%)(500mL)
To solve for V1, we can rearrange the equation:
V1 = (10%)(500mL) / 25%
Now let's calculate the volume V1:
V1 = (10/100)(500mL) / (25/100)
Simplifying the equation:
V1 = (0.10)(500mL) / 0.25
V1 = 50mL
Therefore, you would need to add 50mL of the 25% solution to make 500mL of a 10% diluted solution.
