  • Volumes and molar fractions?

    Hey everyone, I've spent the best part of a day trying to sort out the following question, but still have no real idea how to go about it. If anyone could enlighten me, that'd be awesome!

    "Calculate the volume of toluene you should add to 10.000g of naphthalene to make a solution with a molar fraction of naphthalene equal to 0.9, knowing that the toluene density is 0.867gcm-1 at 20 degrees C"

    Thanks!
