A mixture of sodium chloride $(NaCl)$ and sucrose $(C_{12}{H}_{22}{O}_{11})$ of combined mass $10\mathrm{.}2g$ is dissolved in enough wat The osmotic pressure of the solution is $6\mathrm{.}19$atm at $23\mathrm{.}0C.$ Calculate the mass percent of NaCl in the mixture. Rour Note: Reference the Fundamental constants table for additional information.
