# CHEMISTRY MOLALITY!!!!!

A bottle of wine contains 13.1% ethanol by volume. The density of ethanol (C2H5OH) is 0.789 g/cm3. Calculate the concentration of ethanol in wine in terms of mass percent and molality.

Molality is the number of moles of solute divided by the mass of solvent.

This is solvent NOT solution.

Is this OK?
