The osmotic Pressure of blood is 7.65 atm at 310 k. an aqueous solution of glucose isotonic with blood has the percentage (by volume)

a)5.41%b)3.54%c)4.53%d)53.4%

Answered by admin @ 20/08/2021

Answer:

Let concentration be C

π=CRT

7.65=C×0.0821×310

0.0821×310

7.65

=0.300577M

Molar mass of glucose (C

)=180

weight / volume conc =0.300577×180 g/L

=0.300577×180×10

−3

g/cm

=54.1×10

−3

g/cm

=5.41%
