Question

) The osmotic pressure of blood is 7.65 atm at 270C. How much glucose should be used per litre to prepare an intravenous injection that has the same osmotic pressure as blood?

Answer 1

Answer:

30.88 g/Lt

Explanation:

We know-

molecular mass of glucose = 180

R= 0.0821 Lt atm/K mol

T= 270+273= 543 K

Volume= 1 Lt

osmotic pressure is denoted by π

π = CRT

C is concentration or molarity in g/Lt

C= no of moles/volume

let wt of glucose reqd be x

no. of moles = x/180

7.65 = x/(180×1) × 0.0821 × 54330

on solving,

x = 30.88 g
