Molarity(M)= w/mwt*1000/V
                 Â
Mwt = molarmass of X = 500g/mole
V/v% = 1%
d= density of solute = 5 g/cc
Molarity(M) of diluted solution =Â Â
v/v%*d*10/mwt
                                                        Â
= 1*5*10/500
                                                         Â
= 0.1 M
from dilution law ,
let us consider volume of dilute solution (V2) =100
ml
M1V1 = M2V2
M1 = molarity of standard solution = 2 M
V1 = volume of standard solution take = ?
M2 = Molarity of diluted solution = 0.1
V2 = volume of diluted solution = 100 ml
2*V1 = 0.1*100
V1 = 5 ml
so that ,
dilution factor = Vfinal / Vinitial =100/5=
20
