9.87 Which of the following solutions will give rise to a greater osmotic pressure at equilibrium: 5.00 g of NaCl in 350.0 mL water or 35.0 g of glucose in 400.0 mL water? For NaCl, MW = 58.5 amu; for glucose, MW = 180 amu.
The osmotic pressure of human blood is 7.60 atm. What mass of glucose, C6H12O6, is required to make a 2.00 L aqueous solution for intravenous feeding if the solution must have the same osmotic pressure as blood at body temperature, 37 degrees C? Show all work.
1. Intravenous, or IV solutions used in medicine must exert the same osmotic pressure as blood to prevent a net flow of water into or out of the blood cells. The proper concentration for an intravenous NaCl solution is 0.90 g NaCl per 100. mL of water (sometimes refered to as 0.90% m/v). If the van\'t Hoff factor of NaCl is i = 1.8, what is the osmotic pressure of blood at body temperature, 37

What is the value of the boiling point elevation constant for chloroform? 18. What osmotic pressure in atmospheres would you expect for each of the following solutions? a) 5.00 g of NaCl in 350.0 mL of aqueous solution at 50 °C
1. What is the osmotic pressure exerted by a 4.00 M solution of glucose at 37.0°c? 2. What is the osmotic pressure exerted by a 0.400 M solution of magnesium chloride (MgCl2) at 37.0°C? 3. What is the osmotic pressure exerted by a solution made from combining 30.0 g KI and 250 ml water at 37.0°C?
1.a)The average osmotic pressure of sea water is 30 atm (atmospheres). Calculate the concentration of urea (CH4ON2) at 25 ° C that exerts the same pressure as seawater. R = 0.082 atm L/ mol K 1.b) There is a 1M solution of CH3COOH (acetic acid) in a total volume of 450 mL. What is the molality (m) of the solution? (ρ solution = 1.15 g / mL).
XXIII. An isotonic solution will produce an osmotic pressure of 7.84 atm measured against pure water at human temperature (37.0 °C). How many grams of sodium chloride must be dissolved in 500 mL of water to produce an isotopic solution? Na = 23.00; CI = 35.45 A) 9.01 g B) 4.51 g C) 18.0 g D) none of them
1) Suppose you made an intravenous solution, intended to be isoosmotic to red blood cells (i.e., 300 mOsm). You add 5 grams of NaCl to 800 ml of distilled water. Will this solution be isoosmotic to cells? if not, what will happen to the cells? (Will they take in water or lose water?) How would you make 500ml of a 5% NaCl solution? You dissolve 20 grams of glucose into water to give a solution whose final volume is exactly...
