An aqueous sodium salt (NaCnH2n+1O3) solution has an osmotic pressure of 2.041 atm when 1.068 g of the salt are dissolved in 200. g of water at 25 degrees C. Assuming molality and molarity in such a dilute solution are the same and that the sodium salt is completely dissociated in the solution, determine the formula for the sodium salt.
