Answer:

Step-by-step explanation:

Given

initial volume [tex]V_1=25\ ml[/tex]

initially Molarity [tex]c_1=0.025\ m\ of\ KOH[/tex]

suppose V liter is added to the mixture

To calculate the molarity of diluted solution

[tex]c_1V_1=c_2V_2[/tex]

final volume [tex]V_2=V+25[/tex]

[tex]0.025\times 25=c_2\times (V+25)[/tex]

[tex]c_2=\frac{0.025\times 25}{V+25}[/tex]

[tex]c_2=\frac{0.625}{V+25}\ m[/tex]
