Hi I have a solution of 10ng/mL of a compound of molecular mass 324g/mol. which I have calculated as 3.086x10-11 mol/ml. To get this into mol/L i multiplied this value by 1000 and ended up with 3.086x10-9mol/L. Is this correct?
I also diluted the above solution. If I do a 1:10 dilution is the concentration 3.086x10-10, a 1:100 dilution 3.086x10-11, and so on.
Would be greatful for any help you can give.
