In  same way, compute metal ratio:

Cu/Zn = x / 1-x

for these values of x, you get the ratio of the metals. With the volume and concentration of CuCl2 you can get the quantities you require.

Can you re frame your question?  

Dear  Fernando Acosta-Humánez,

Thanks.i want to synthesis Zn1−xCuxS nanoparticles that Cu is doping agent with dopant content ranging from x=0.00,0.05, 0.10 .

I  prepare 0.1 M CuCl2 50 ml  ,So for x=0.00 ,1.oo ,2.00 , how much CuCl2  need in ml,respectively?

please answer for 0.1 M CuCl2 50 ml  and x=0.00 ,1.oo ,2.00 , how much CuCl2  need in ml,respectively.
