Solution
The osmotic pressure of blood is 7.65 atm at 310 K. An aqueous solution of glucose isotonic with blood contains 54.1 g of glucose in 1 L of solution.
Explanation:
M2 = `("W"_2"RT")/(π"V")`
`"W"_2/"V" = (π"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
= 54.1 g L−1
