please help. i've determined the concentration of a solution to be 4.3nM

This was done my taking 0.5ml of (1mg/mL) solution and combining to 2ml of another solution. so total volume was 2.5ml.

after calculations, i get 4.3mM for that solution. how do i convert this to nM/gram of stuff? MW is 278.

thanks
