Accurate theoretical predictions of the volume-fraction dependence during diffusion-controlled coarsening of a polydisperse assembly of particles have proved difficult. Here, a new model of ...

Osmolarity = Molarity (M) × Number of particles (i) × 1000. Where: – M = Moles of solute per liter of solvent – i = Number of dissociable particles produced by one molecule of solute – 1000 = ...
