Question

I need help on question 2 to find out the molality of the NaCI in the solution, so the mass of NaCI 12 grams.

For each calculation, you will be required to show detailed work steps. Make sure the number of each question is clear according to what was in the introductions and procedure document. Meaning, make sure that your use of the template doesn't mess up the numbering! Post lab questions 1) Find the percent by mass of NaCl in solution Use Equation editor here to show all your work! You can copy and paste these when you need more lines % by mass NaCl Put your answer here with units! 2) Find the molality of NaCl in solution Use Equation editor here to show all your work! You can copy and paste these when you need more lines molality of NaCl Put your answer here with units! 3) Find the density of solution Use Equation editor here to show all your work! You can copy and paste these when you need more lines density Put your answer here with units! 4) Find the molarity of NaCl in solution Use Equation editor here to show all your work! You can copy and paste these when you need more lines molarity Put your answer here with units! 5) Consider the solution to consist of three distinct particles: water molecules, sodium ions and chloride ions. Find mole fraction of water in the solution Use Equation editor here to show all your work! You can copy and paste these when you need more lines Xwater Put your answer here with units! 6) Difference in measured boiling points of water and solution (based on direct observations) Use Equation editor here to show all your work! You can copy and paste these when you need more lines Observed difference in boiling points Put your answer here with units! 7) Expected AT from calculation based on the concentration (you may assume the van't Hoff factor is based on the chemical formula). Use Equation editor here to show all your work! You can copy and paste these when you need more lines Expected difference in boiling points Put your answer here with units!
