Question

9. Human blood has osmotic pressure of 7 .2 atm at body temperature
37°C Calculate the molar concentration of solute particles in blood
Gthat R=0.0821 L atm K​

Answer 1

Answer:

Explanation:

Л = CRT

or C = Л/RT

Л = 7.2 atm

R = 0.0821 L atm K-1 mol-1

T = 37°C = 37 + 273 = 310 K.

Molar concentration (C) = (7.2 atm)/(0.082L Latm K-1mol-1 ) x (310 K)

= 0.283 mol-1

= 0.283 M
