Answer: The volume of concentrated sucrose solution required is 0.68 mL
Explanation:
To calculate the volume of concentrated solution, we use the equation:
[tex]M_1V_1=M_2V_2[/tex]
where,
[tex]M_1\text{ and }V_1[/tex] are the molarity and volume of the concentrated sucrose solution
[tex]M_2\text{ and }V_2[/tex] are the molarity and volume of diluted sucrose solution
We are given:
[tex]M_1=5.0M\\V_1=?mL\\M_2=0.040M\\V_2=85.0mL[/tex]
Putting values in above equation, we get:
[tex]5.0\times V_1=0.040\times 85.0\\\\V_1=\frac{0.040\times 85.0}{5.0}=0.68mL[/tex]
Hence, the volume of concentrated sucrose solution required is 0.68 mL
