Question

The total concentration of dissolved particles inside red blood cells approximately 0.30 M and the membrane surrounding the cells is semipermeable. What would the osmotic pressure (in atmosphere ) inside the cells become if the cells were removed from the blood and placed in pure water at 298 K?

• A. 7.34 atm
• B. 1.78 atm
• C. 2.34 atm
• D. 0.74 atm

Answer 1

The correct option is A 7.34 atm

concentation of dissolve particle $C=0.30M$

Osmotic pressure $\pi =CRT$

$=0.3\times 0.0821\times 298$

$=7.34atm$
