Answer 1

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
