Question

Compelete the following statements by selecting the correct alternative from the choices given:
(1) Human blood is isotonic with $0.9$ NaCl solution at ${27}^{o}c$ C. What is osmotic pressure?

• A. $8.6atm$
• B. $15.2atm$
• C. $4.8atm$
• D. None of these

Answer 1

The correct option is D None of these

Since, human blood is isotonic with given $NaCl$ solution, it will have same osmotic pressure as this $NaCl$ solution.

$\therefore \pi =CRT$

$=0.9\times 0.0821\times 300$

$=22.167atm$
