Detailed Solution

Given data: It is given to identify average osmotic pressure of human blood is 7.4 atm at 27°C, then total concentration of various solutes is

Explanation

Human blood has an average osmotic pressure of 7.4 atm at 27 °C, and the total concentration of different solutes is

The least amount of pressure that must be applied to a solution in order to stop solvent molecules from passing through a semipermeable membrane is known as osmotic pressure (osmosis). It is a collaborative property that is reliant on how many solute particles are present in the solution.

Cgluoose =7.4 atm1×0.0821atmLmolk×(273.15+25)k


Cgluoose =0.3molL-1

Hence, the correct option (C). 0.3molL-1
