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

Step-by-step 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* 1.95=M_2* 100\\\\M_2=(0.806* 1.95)/(100)=0.0157M`

Hence, the concentration of diluted bleach solution is 0.0157 M
