concentration of starting material - (Jul/11/2016 )

Please help me with this conversion. I have a 1 mg/ml of solution that has molecular weight of 850. What is the concentration of the solution in mM?


thanks in advance.


850 g/liter=1 M

850 mg/liter=1 mM

850 ug/ml=1 mM

(1mg/ml)/(850 ug/ml)=1.176 mM
