Dear all,
I'm confusing about the preparation of a solution I should to use.
I have a solution NaCl 12% and I have to prepare 9 % in 8 ml.
How can I do ?
I don't thing the 3 basis rule (C1V1=C2V2) would work, right?
Thank you for help

of course it can:
12%xv1=9%x8ml
v1=(9x8)/12=6ml
12%xv1=9%x8ml
v1=(9x8)/12=6ml
talent does what it can
genius does what it must
i do what i get paid to do
