You are stranded on a lifeboat with several other people in the middle of the ocean. You have run out of clean drinking water and are very thirsty. The others have started to drink the seawater to quench their thirst. Since you’re waiting for rescue (and are a top notch AP Biology student), you decide to solve a couple of water potential problems to determine if drinking sea water is a good idea or not.
a) The majority of dissolved ions in seawater is NaCl, roughly a 0.5M concentration. The ionization constant of NaCl is 2.0. Calculate the solute potential for seawater if you know that the water is 2°C.
b) Your own cells have a 0.15M concentration. Calculate the solute potential for your own cells, knowing that body temperature is 37°C.
c) Using your knowledge about water potential, if you drink the seawater, wat will happen when the seawater comes into contact with your body’s cells? Note: ΨP for animal cells is zero
What is the molarity of the following solution: 47g of KCl dissolved in enough water to give 375 mL of solution
The normal range of the sodium electrolyte in the body is 134 to 145 mEq/L. The term mEq is dependent on the charge of the ion. Since sodium is a +1 ion, 134 mEq/L is the same as 134 mmol/L.
An ion that has a greater positive or negative charge; however, will have 1 mEq for each positive or negative charge of the ion for every 1 mmol. For example, for Ca+2, 2mEq/1mmol.
If the standard range of Magnesium in the body is 0.70 to 0.95 mmol/L, convert this value into mEq/L for the Mg2+ ion. (Use dimensional analysis to figure this out)

The researcher then uses an experimental apparatus ,where he notes that, at room temperature (300K) and atmospheric pressure (101.325 kPa), distilled water flows naturally into the solution compartment. However, when he applies an extra pressure of 1000 Pa he observes that the flow of distilled water ceases and the system is in balance. Calculate the molar mass of this protein, in kDa (1 Da = 1 g/ mol); Why does the flow of distilled water cease with the application of the pressure of 1000 Pa?
