What is the molality and mole fraction of sodium chloride in a solution

prepared by dissolving 29.5 g NaCl into 212.7 g of H2O?

Would the molaity be 2.37 m NaCl and would the mole fraction be 0.0410?

m is correct. X_NaCl is correct. Good work.

Did you know?

Did you know that molality is a measure of the concentration of a solute in a solution, expressed in moles of solute per kilogram of solvent? In the given example, the molality of sodium chloride (NaCl) in the solution prepared is calculated to be 2.37 m NaCl, meaning there are 2.37 moles of NaCl dissolved in every kilogram of water (H2O). Furthermore, the mole fraction is another way of expressing the concentration of a solute in a solution. It is the ratio of the moles of a specific component to the total moles of all components in the solution. In this case, the mole fraction of NaCl in the solution is calculated to be 0.0410, indicating that approximately 4.10% of the total moles in the solution are NaCl. Understanding these concepts allows chemists and scientists to analyze and predict various properties and behaviors of solutions, making them fundamental in the study of chemistry.
