A student has 500.0 mL of a 0.1111 M aqueous solution of NazCO3 to use in an experiment. She accidentally leaves the container uncovered and comes back the next week to find only a solid residue. The mass of the residue is 15.90 g. Determine the chemical formula of this residue. If the substance is a hydrate, use a period instead of a dot in its formula.
