The total concentration of dissolved particles in blood is 0.30 M. An intravenous (IV) solution must be isotonic with blood, which means it must have the same concentration.
(a) To relieve dehydration, a patient is given 190. mL/h of IV glucose (C6H12O6) for 2.0 h. What mass (g) of glucose did she receive?
(b) If isotonic saline (NaCl) is used, what is the molarity of the solution?
(c) If the patient is given 160. mL/h of IV saline for 3.0 h, how many grams of NaCl did she receive?

The total concentration of dissolved particles in blood is 0.30 M. An intravenous (IV) solution must be isotonic with blood, which means it must have the same concentration. To relieve dehydration, a patient is given 100 mL/h of IV glucose (C_6H_12O_6) for 3.0 h. What mass (g) of glucose did she receive? g

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...

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

The nurse must prepare the correct intravenous (IV) solution before administration. The prescription reads for the patient to receive D5½ NS with 40 mEq KCl/L at 125 mL/hr. The nurse must add KCl to the IV because no premixed solutions are available. The unit medication supply has a stock of KCl 3 mEq/mL in multidose vials. What amount of KCl should be added to a liter of D5½ NS to obtain the correct solution? Give your answer using one decimal...

Colligative properties, such as boiling point elevation, depend on the number of dissolved particles in solution. For nonelectrolytes, no dissociation occurs, and so you can use the number of moles of solute to calculate both molality and molarity. In contrast, electrolytes dissociate, and therefore the molality and molarity must be calculated based on the number of moles of dissociated particles or ions. There are two ions per formula unit of NaCl. Therefore, we would expect the freezing-point depression ΔTf of...

74 Percent Concentration -The amount of solute dissolved in a fixed amount of solvent is called the concentration of the solution. Concentrations are typically expressed as Mass al.) (% m/m) which is the mass of the solute (g) divided by the mass of the solution [solute+ solvent] (g)x 1000/0; or as Volume ol.) (% v/v ) which is the volume of the solute in a fixed volume of solution (1O0mL of solution) x 1000/0; or less commonly in the laboratory,...
