Question

You are given a 0.1m solution of glucose (stock solution). The stock solution required to make 0.5 ml of 0.005m glucose solution (rounded off to three decimal places) in ml is

Answer 1

Answer:

which class bhai and which board you have

Answer 2

The volume of stock solution needed is 0.025 mL

Explanation:

To calculate the molarity of the diluted 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 tock glucose solution

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

We are given:

$M_1=0.1M\\V_1=?mL\\M_2=0.005M\\V_2=0.5mL$

Putting values in above equation, we get:

$0.1\times V_1=0.005\times 0.5\\\\V_1=\frac{0.005\times 0.5}{0.1}=0.025mL$
