Question

The osmotic pressure of blood is $7.65$ atm. at $310$K. an aqueous solution of Glucose that will be isotonic with blood is ________ wt/Vol.

• A. $5.41\%$
• B. $54.1\%$
• C. $3.5\%$
• D. $4.53\%$

Answer 1

Answer: (B)

$54.1\%$

$\pi =cRT$

Osmotic pressure of blood $\pi =7.65atm$

$R=0.082$

$T=310K$

$7.65=c\times 0.082\times 310$

$c=0.3009m$

Hence the amount of glucose per liter

$0.3\times 180=54gmperliter$
