Chapter 13.7, Problem 13.13PSP

Interpretation Introduction

Interpretation:

The molar mass of hemoglobin has to be calculated.

Concept Introduction:

Osmosis is the process by which net movement of solvent into an expense of higher solute concentration via semi permeable membrane.

Osmotic pressure is the pressure that is needed to stop osmosis. Osmotic pressure of the solution is directly proportional to the concentration of the solution. We can calculate osmotic pressure by using this formula is given by,

Osmotic pressure $\text{(π) = icRT}$

Where,

  ‘i’-van’t Hoff’s factor

  c – Concentration of the solution (mol/L)

  R- Ideal gas constant ($0.08206{\text{L atm mol}}^{\text{-1}}{\text{K}}^{\text{-1}}$)

  T-Temperature in Kelvin

From given mass of substance moles could be calculated by using the following formula,

  $\text{Moles}\text{of}\text{substance }\text{= }\frac{\text{Given}\text{mass}\text{of}\text{substance}}{\text{Molecular}\text{mass}}$
