The molarity and the molality of a solution prepared by dissolving 2.00 g of ethanol C2H5OH with 99.0 g of water to give a final volume 101 mL are
______Molarity and _______molality.
How do I do this?
Remember the definitions. That's all you need.
molarity = # mols/L solution.
molality = # mols/kg solvent.
# mols = grams/molar mass.
