Osmotic pressur of blood is 7.65 atm at ...

Osmotic pressur of blood is 7.65 atm at 310K. An aqueous solution of glucose that will be isotonic with blood is …….wt./vol.

A

5.41

B

3.54

C

4.53

D

53.4

Text Solution

Verified by Experts

The correct Answer is:
A
Since glucose and blood are isotonic, the osmotic pressure are the same. Therefore, `pi_(glucose)=pi_(blood)`
Or `7.65xx"V"="W"/180xx0.0821xx310` [w=amount of glucose present in V litres of solution]
Or `7.65xx180=W/Vxx0.0821xx310`
Or `W/V=(7.65xx180)/(0.0821xx310)=54.1g " L"^(-1)` or 5.41%
