You have 846 ml of 3.95 m hcl. using a volumetric pipet, you take 268 ml of that solution and dilute it to 803 ml in a volumetric flask. next, you take 100.00 ml of that solution and dilute it to 184 ml in a volumetric flask. what is the concentration of hydrochloric acid in the final solution?

The concentration of hydrochloric acid in the final solution is 0.72 M

Explanation:

According to the dilution law,

where,

= molarity of stock solution = 3.95 M

= volume of stock solution = 268 ml

= molarity of diluted solution = ?

= volume of diluted solution = 803 ml

Next, you take 100.00 ml of that solution and dilute it to 184 ml in a volumetric flask.

According to the dilution law,

where,

= molarity of stock solution = 1.32 M

= volume of stock solution = 100 ml

= molarity of diluted solution = ?

= volume of diluted solution = 184 ml

Thus concentration of hydrochloric acid in the final solution is 0.72 M

the answer is d.) potassium
