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

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
