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.

Respuesta :

Answer: The concentration of diluted bleach solution is 0.0157 M

Explanation:

To calculate the molarity of the diluted solution, we use the equation:

[tex]M_1V_1=M_2V_2[/tex]

where,

[tex]M_1\text{ and }V_1[/tex] are the molarity and volume of the concentrated bleach solution

[tex]M_2\text{ and }V_2[/tex] are the molarity and volume of diluted bleach solution

We are given:

[tex]M_1=0.806M\\V_1=1.95mL\\M_2=?M\\V_2=100mL[/tex]

Putting values in above equation, we get:

[tex]0.806\times 1.95=M_2\times 100\\\\M_2=\frac{0.806\times 1.95}{100}=0.0157M[/tex]

Hence, the concentration of diluted bleach solution is 0.0157 M
