Answer: The volume of stock solution needed is 0.016 L

Explanation:

To calculate the volume of stock 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 stock solution

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

We are given:

$M_1=12M\\V_1=?L\\M_2=0.10M\\V_2=2L$

Putting values in above equation, we get:

$12\times V_1=0.1\times 2\\\\V_1=0.016L$

Hence, the volume of stock solution needed is 0.016 L
