How much of a 5.0 M sucrose solution should you use to make 85.0 mL of a 0.040 M solution?

Solution 88P:

Here, we are going to calculate the required volume of 5.0 M sucrose to make 85.0 mL of a 0.040 M solution by using dilution equation.

M1V1= M2V2 ------(1)

Where, M1 and V1 are Molarity and volume of the initial solution whereas M2 and V2 are the Molarity and volume of the solution.

From the Question,

It is given that,

M1 (initial Molarity) =0.040 M

V1 (initial volume) = 85.0 mL

M2 (final Molarity) =5.0 M

V2 (initial volume) = ?

Thus, from equation (1)

M1V1= M2V2 ------(1)

V2 = M1V1/M2

= = 0.68 mL

Thus, 0.68 mL of 5.0 M sucrose solution is required to make 85.0 mL of a 0.040 M solution.
