When I solve your equation V1 X 1560 ug/ml = 10ml X 0.8 ug/ml I get .005 ml. Therefore the dilution would be closer to 1:2000. I would usually divide the 1560 ug/ml by 0.8 ug/ml and get 1950 therefore 1:1950 would be more accurate . Tom T -Original Message- From:

Here's how I approach this problem. Convert all concentrations into the same units. I prefer to use whichever the final concentration unit is, so it looks like this: 1.56 mg/ml = 1560 ug/ml You have 1560 ug/ml and you need 0.8 ug/ml Divide 1560 by 0.8 = 1950. So your final dilution is 1:1950.
