Question

How much 2.0 M solution of glucose (C6H1206) is required to prepare 0.15 L of 0.15 M solution? 36 mL 30 ml 113 mL 1.67 ml 11.3 ml

Answer 1

Answer: The volume of 2.0 M solution of glucose required is 11.3 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 solution

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

We are given:

Conversion factor: 1 L = 1000 mL

`M_1=2.0M\\V_1=?mL\\M_2=0.15M\\V_2=0.15L=150mL`

Putting values in above equation, we get:

`2.0* V_1=0.15* 150\\\\V_1=11.3mL`

Hence, the volume of 2.0 M solution of glucose required is 11.3 mL
