Order Tonicity Moles and Osmoles Discussion
1. What information does the molarity of a solution provide?
A. the density of a solution
B. the number of dissolved particles per litre of solution
C. the mass of a mole of the substance
D. the tonicity of the solution
2. What term is applied to an intravenous solution that would cause a net movement of water out of red blood cells?
A. hypertonic
B. supertonic
C. epitonic
D. hypotonic
3. What is a definition of an osmole? The amount of substance that:
A. must be dissolved to produce 6×1023 solute particles.
B. must be dissolved to produce an osmotic pressure of 1.0 mmHg.
C. must be dissolved to produce an isotonic solution.
D. contains 6×1023 particles.
4. Choose the solution below that has the lowest concentration of dissolved
A. 0.9% NaCl
B. isotonic powerade
C. 5% glucose
D. hypotonic saline
5. What can be correctly said of an isotonic intravenous solution? An isotonic
A. causes water to move out of red blood cells.
B. causes no net movement of water into or out of red blood cells.
C. has the same solutes in the same solution concentration as blood plasma
4 Chemistry for Physiology
D. causes water to move into red blood cells.
6. What would be the concentration of a solution that causes red blood cells placed
in it to swell?
A. hypotonic
B. isotonic
C. hypertonic
D. iso-osmotic
7. The unit milliosmoles per litre (mosmol/L) refers to which of the following?
A. the number of particles in solution, in multiples of 6×1020 per litre.
B. 103
times the number of moles of particles in a litre of solution.
C. the number of molecules per litre of solution.
D. the number of moles per millilitre of solution.
8. A hypertonic solution is one which
A. has an osmotic pressure that is different to that inside red blood cells
B. has an osmolarity less than that of red blood cells
C. causes no net movement of water through the membrane of red blood cells
D. has an osmolarity greater than that of red blood cells
9. Given that one mole of Na Cl− has a mass of 58.5 g, what would be the concentration of particles when 0.9 g of Na Cl− is dissolved in 100 ml of water?
A. 117 mmol/L
B. 150 mmol/L
C. 150 mosmol/L
D. 300 mosmol/L
Ans:=D: the number of moles in 0.9 g=0.9 g/58.5 g/mol=0.0154 mole of
Na Cl−. However NaCl separates into ions when dissolved, so that there will be
0.0154 mol of Na and 0.0154 mol of Cl, hence 0.0308 osmol of particles=30.8 mosmol per 100 ml. In one litre, the number of moles would be ten
times greater, so 300 mosmol/L (is closest).
