0.000341 g fluorescein (332.32 g/mol) is dissolved in 255 mL solution of ethanol. The density of ethanol is 0.785 g/mL.

What is the concentration of the solution in molarity (M)?

    nevermind, got it!

  • Chemistry -

    mols fluorescein = grams/molar mass
    M = mols/0.255L soln.

    thank you i figured it out right before you posted this :)
