Please help I'm not sure how to solve these. A solution is prepared by dissolving 20g of NaCl (f.w.= 58.44 g mol^-1), a nonvolatile solute, in enough water (m.w. = 18.02 g mol^-1) to result in exactly 1 L of solution at 25 C. The density of the solution is 1 g mL ^-1. How do you calculate freezing point of the solution as well as vapor pressure and the osmotic pressure? I understand boiling point.
Beyond the Course: Your beverage company is branching out from added sugar in their beverages to make a drink where the main ingredient is fresh-squeezed orange juice, called Beverage C. Yum! The beverage will still be subjected to the same taxes as Beverages A & B, so determining sugar content is still vital. Suggest a method of reliably examining the sugar concentration in each batch of Beverage C. Some considerations to address: Do you want to measure the same property for Beverage C as you did for Beverages A & B? ● Can you use the same calibration curve as you did for Beverages A & B? Describe the considerations you made when determining your method.
You want to isolate the caffeine content of your hot drink usingrecrystallization. It is known that 100 ml of the hot drink contains 65 g ofcaffeine. The solubility of caffeine in hot and cold water is 660g/L ofwater and 10g/L of water respectively. What is the highest possiblerecovery for this process? Solubility: The amount of solute that can bedissolve per amount of solvent.
