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

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
