Answer : The volume for 6.0m HCl solution required = 62.5 ml
Solution : Given,
Initial concentration of HCl solution = 6.0m
Final concentration of HCl solution = 1.5m
Final volume of HCl solution = 250 ml
Initial volume of HCl solution = ?
Formula used for dilution is,
[tex]M_1V_1=M_2V_2[/tex]
where,
[tex]M_1[/tex] = initial concentration
[tex]M_2[/tex] = final concentration
[tex]V_1[/tex] = initial volume
[tex]V_2[/tex] = final volume
Now put all the given values in above formula, we get the initial volume of HCl solution.
[tex]6.0m\times V_1=1.5m\times 250ml[/tex]
[tex]V_1[/tex] = 62.5 ml
Therefore, the volume for 6.0m HCl solution required = 62.5 ml
