उत्तर

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) 5.41%.

Explanation:

`"M"_2 = ("W"_2"RT")/(pi "V")`

`"W"_2/"V" = (pi "M"_2)/"RT"`

`= (7.65  "atm" xx 180  "g mol"^-1)/(0.08205 "atm" "dm"^3 "K"^-1 "mol"^-1 xx 310 "K")`

= 54.1 g dm-3 = 5.41 g cm-3 = 5.41%
