Question
The average osmotic pressure of human blood is 7.8 bar t 37oC. What is the concentration of an aqueous NaCl solution that could be used in the blood stream ?
Options
A.0.16 mol/L
B.0.31mol/L
C.0.60 mol/L
D.0.45 mol/L
Solution
π = cRT
7.8 = c × 0.082 × 310
c =
= 0.31 mol/L
7.8 = c × 0.082 × 310
c =
= 0.31 mol/LCreate a free account to view solution
