What is the molarity of the solution prepared by diluting 25.0ml of 0.220M NaCl to 75.0ml of final volume?( explain your steps)

• Chemistry -

There is no "explanation" as I see it.
mL x M = mL x M is the dilution formula or you can do it as
0.220M x (25/75) = ??
Also, you can say you have diluted it by a factor of 3 (25 to 75); therefore, it must be 1/3 of the original concn.
