CHEMISTRY MOLALITY!!!!!

posted by Anonymous

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?
