need chemistry help!!?
working on a project an cannot figure out how to get the total concentration of a whole solution. we are using..
5 microL of ethanol (density .79g/ml and molecular weight of 30 g/mol)
1mg of a compound known as pgf (molecular weight of 475.62 g/mol)
I am so lost and dont know where to start.. please help!!

You did not say how you want the answer. Moles PgF per L? But here goes. Let uL denote microliter. Let ethanol be called EtOH.
1mgPgF/5uLEtOH x 1gPgF/1000mGPgF x 1molPgF/475.62gPgF x 1x10^6ul/L = 0.420 mole/L PgF
That is the concentration in moles per L.
