Question

Once of the skills necessary for this experiment is dilution. If you have 1.95 mL of .806 M bleach, what will be the new concentration if the bleach is diluted to 100 ml in a volumetric flask? Report answer to 4 decimal places. Do no include units.

Answer 1

Answer: The concentration of diluted bleach solution is 0.0157 M

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 concentrated bleach solution

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

We are given:

$M_1=0.806M\\V_1=1.95mL\\M_2=?M\\V_2=100mL$

Putting values in above equation, we get:

$0.806\times 1.95=M_2\times 100\\\\M_2=\frac{0.806\times 1.95}{100}=0.0157M$

Hence, the concentration of diluted bleach solution is 0.0157 M
