Question
A glucose solution is isopiestic with blood. What is the osmolarity of glucose solution?
Options
A.0.31 M
B.5.5 M
C.3.1 M
D.0.154 M
Solution
Isopiestic refers to the same pressure. Blood is isotonic with 0.9% (w/v) NaCl solution.
$\therefore\text{ Osmolarity = }\frac{0.9/58.5}{100/1000} \times 2 \approx 0.31\text{ M}$
