log MN=log + log (answer)
If I understand the question, this is just a property of logs. The log of a product is the sum of the logs. log (M * N) = log (M) + log (N)

Actually, this is true. Sodium Carbonate, Na2CO3, is an ionic compound that contains covalent bonds within the carbonate anion.
the Van't Hoff factor is always positive. Kf for water is -1.86 Kelvin/molal. Your works is otherwise correct, you're just missing the negative sign on Kf. Hope this helps.
The periodic table will give you the answers you are looking for here. The molar mass of oxygen is 16.00, and Carbon is 12.01. Adding these together you get a total of 28.01g/mol, rounding everything to two decimal places.
