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.
i don't know how to get molality. please help!!!!
Molality is the number of moles of solute divided by the mass of solvent.
This is solvent NOT solution.
Is this OK?
