Answer:

V₁   = 208.3 mL

Explanation:

Given data:

Initial molarity of HCl  = 6.0 M

Final volume = 500 mL

Final molarity = 2.5 M

Volume of initial solution required = ?

Solution:

Formula:

M₁V₁   =  M₂V₂

Now we will put the values in formula.

6.0 M × V₁   = 2.5 M ×500 mL

6.0 M × V₁   = 1250 M.mL

V₁   = 1250 M.mL / 6.0 M

V₁   = 208.3 mL
