A mixture is to eb anlysed for penicllin. You add 10.0 mg fo penicllin labelled with .^(14)C that has a specific activity of 0.785mu Ci mg^(-1). From this mixture you are able to isotlate only 0.42 mg of pure penicllin. The specific activity of the isolated pen,om od 0.102mu Ci mg^(-1). How much penicllin was in theoriginal mixture?
