What is the molarity of a kcl solution made by diluting 75.0 ml of a 0.200 m solution to a final volume of 100. ml?

The  molarity of  KCl  solution    made  by  diluting  75.0 ml   of a  0.200M  solution   to a final  volume  of 100ml  is  calculated  using  the  below  formula

M1V1=M2V2
M1=0.200 M
V1=  75.0  Ml
V2= 100 ml
M2=?

by  making M2  the formula  of  the  subject   M2  =M1V1/V2
=75.0  ml  x0.200 M/100 Ml  =  0.15 M
