The vapor pressure over an ethanol solution containing a non-volatile solute is 5% lower than the vapor pressure over a pure ethanol solution. What is the osmotic pressure of the ethanol solution containing the non-volatile solute at 20°C given that the molar volume of ethanol at 20°C is 58.37 mL/g-mol.

answer; protein;

lol idk man i guess u gotta ask bill nye the science guy

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
