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...
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

2. A patient receives 2.5 L of intravenous (IV) glucose solution. If the liquid contains 5.0 g glucose per 100.0 mL of solution, then calculate the number of kilocalories that the patient receives from the glucose solution. Note, the caloric value of glucose is 4 kcal/g. 3. Why are fats well suited for energy storage in the body? 39
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...
8. Which beaker contains more dissolved glucose particles? Solution A Solution B 50.0 mL of 1.25 M glucose solution. 50.0 mL of 25 % (m/m) glucose solution. Molar Mass Glucose - 180.156 g/mol Density of 25% solution = 1.56 g/mL
Glucose solutions used for intravenous medical applications are typically 5.00 % (m/m) Glucose dissolved in water. What is the molarity associated with a typical 5.00 % Glucose solution. Molar Mass (Glucose) = 180.16 g/mol; Density of normal glucose solution = 1.01 g/mL 0.280 M b) 0.364 M c) 2.75 M d) 3.57 M e) 9.09 M
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...
6. 2.50 grams of nicotine (C10H14N2) was dissolved in 150.0 g of dichloromethane. What is the concentration of that solution in molality? b. In mole fraction? 7. How many grams of sucrose (C12H220.1) do you need to make 500.0 mL of a 0.050M solution? 8. Some intravenous sugаr solutions are 5.0% glucose (C.H1206) by mass. How many grams of glucose are in a 1.0L IV bag if the density of the solution is 1.01 g/mL.
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,...
