Percent and Mole Solutions

  1. Calculate the mass percent of a solution containing 40.0grams of solute and 160.0 grams of solvent.




  2. Calculate the molarity of a solution containing 4.0 moles of solute that has a total volume of 2.0L.




  3. Calculate the mass percent of a solution containing 450.0grams of solute and 1250.0 grams of solvent.




  4. Calculate the molarity of a solution containing 4.6 moles of solute that has a total volume of 1.2L.




  5. Calculate the mass percent of a solution containing 4.0grams of solute and 175.0 grams of solvent.




  6. Calculate the molarity of a solution containing 400.0 grams of a solid that has a molecular mass of 60.0 grams per mole and that has a total volume of 2.0L.




  7. Recalculate your answer in problem #6 only now with the solid having a molecular mass of 140.0 grams per mole instead of 60.0.
