Question

under the derms of the skin. Tus II S UV y Puomu solution A has a lower solute concentration (or lower osmolality) than solution B. The prefix hyper means above or greater. For example, a hyperactive kid has a greater activity level than a normal kid. In the above example, B has a greater solute concentration than A, thus B is hyperosmotic to A. The prefix iso means the same or equal. Two solutions that are isosmotic to each other have the same solute concentrations. 6. Consider the following red blood cells: 7 RBC 0.9% NaCl RBC 0.9% NaCl • RBC · 0.9% Naci Solution I = 25% NaCl Solution II = 0.2% NaCI Solution Il = 0.9% NaCI Figure 3-2: Red Blood Cell Solutions 7. Which of the solutions surrounding the RBC are: a. Hyperosmotic (hypertonic) to the cell? b Isosmotic (isotonic) to the cell? C. Hyposmotic (hypotonic) to the cell? 8 What is the percentage of water in red blood cells? 9. What is the percentage of solvent in: a. Solution I? b. Solution II? c. Solution III? d. The red blood cells?

Answer 1

© Solution I = 25%. Nach because Solute concentration in outer solution is higher than inney RBC solute concentration 07 Soluhen U = 0.9 %Nach Lbecause solente concentration for outer Sowon and RBC are same] 6 Solution I = 0.2%. Nalle [because solate concentration of RBC is higher than outer solution hence water move into cell and cell swell up RBC contain 92% water and 8% of blood blama brodems and prace congunit of other material so © Solution I = 757 by Solution I = 99,8% (RBC = 92% ① solution il = 99.1% 6 As, we know, % Solution = (Solvent + Solute) % So, ③ .. (100- 25) % 75%, 25% - Solute Nach, O. (100-012) 7 = 99,8% 0.27.-Salute Nall. © - Cloon 0.g) pogg.17 og/solute Nol. RBC -92% water means 92% solvent.
