Question:

What volume of 4.00 M sodium hydroxide must be diluted to make 300 mL of a 0.688 M sodium hydroxide solution?

(a) 2.64 mL

(b) 51.6 mL

(c) 26.4 mL

(d) 29.3 mL

Dilution Law:

Molarity is defined as moles of solute per unit volume of solution.

Dilution law is given by -

{eq}\rm M_1V_1 = M_2V_2 {/eq}

Where

{eq}\rm M_1 ~and~M_2 {/eq} are the molarity of stock and diluted solution respectively.

{eq}\rm V_1~and~V_2 {/eq} are the volume of stock and diluted solution respectively.
