Question

What is the molar concentration of particles in human blood if osmotic pressure is 7.2 atm?

Answer 1

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
