Answer: The volume of concentrated sucrose solution required is 0.68 mL

Step-by-step explanation:

To calculate the volume of concentrated solution, we use the equation:

M_1V_1=M_2V_2

where,

$M_1\text{ and }V_1$ are the molarity and volume of the concentrated sucrose solution

$M_2\text{ and }V_2$ are the molarity and volume of diluted sucrose solution

We are given:

$M_1=5.0M\\V_1=?mL\\M_2=0.040M\\V_2=85.0mL$

Putting values in above equation, we get:

$5.0* V_1=0.040* 85.0\\\\V_1=(0.040* 85.0)/(5.0)=0.68mL$

Hence, the volume of concentrated sucrose solution required is 0.68 mL
