The osmolality of A. A solution determines its freezing point. B. Intracellular fluid is about twice that of extracellular fluid. C. 1.8 per cent sodium chloride is about twice that of normal plasma. D. 5 per cent dextrose solution is about five times that of 0.9 per cent saline.E. Plasma is due more to its protein than to its electrolyte content. |

Answer» A. True Depression of the freezing point is an index of a solution’s osmolality. B. False Their osmolality is the same; osmotic water movements ensure that this is so. C. True Plasma has the tonicity of a normal saline solution (0.9 per cent sodium chloride). D. False They have the same number of particles. E. False Proteins account for only 1 per cent of plasma osmolality. |
