If a chemist wants to make 575 milliliters of 0.75 m hcl solution from a stock solution of 2.0 m hcl, how many milliliters of the stock solution would the chemist need to use

The answer is 216 mL

Answer : The volume of stock solution will be, 215 ml

Solution :

According to the neutralization law,

where,

= molarity of HCl solution = 0.75 M

= volume of HCl solution = 575 ml

= molarity of stock solution = 2.0 M

= volume of stock solution = ?

Now put all the given values in the above law, we get the volume of stock solution.

Therefore, the volume of stock solution will be, 215 ml
