WebAvogadro's number is defined as the number of elementary particles (molecules, atoms, compounds, etc.) per mole of a substance. It is equal to 6.022×10 23 mol-1 and is expressed as the symbol N A. Avogadro's number is a similar concept to that of a dozen or a gross. A dozen molecules is 12 molecules. A gross of molecules is 144 molecules. how to make jackfruit bbqWebThe slope of this curve is the diffusion constant, which then yields an estimate for k B via Stokes-Einstein. To recover Avogadro's constant, you need the ideal gas constant R, which is measured through independent means; typically via macroscopic thermodynamic experiments which probe the slope in p V = n R T.
