You may rework problems and resubmit answers as many times as you wish, to improve your score. There is a retry delay of 2 minutes between answer submissions for any single question. Most questions are customized, so the correct answers are different for each student. A checkmark will appear to the left of each corectly solved problem. gned Exercises 1. The total concentration of dissolved ions in seawater is about 1.1 M, but concentrations can vary depending on the exact location and conditions. What minimum pressure system in order to overcome the osmotic pressure in water that is 1.1 M in total dissolved ions at 18 C? Enter the comect numeric value to 2.0% precision. Express scientific notation like 4.29E-15 bar Grade This Exercise 2. What mass of salt would have to be added to 1050.0 mL of water in order to raise the boiling point of the solution by 0.5 C?
