13 Concentration Of Solution Mass of the solute in a given volume of solvent.Mass/Volume e.g.12 g. of NaCl dissolved in 3L H2O=12g./3 l or g/L
14 In A Solution Molecules Are Moving Constantly They Collide and Bounce off each otherThis causes them to spread out randomlyResulting In:Movement from an area of higher concentration to and area of lower concentration
15 DIFFUSIONMolecules move away from an area of Higher Concentration to area’s of Lower ConcentrationEquilibriumConcentration of a solute is the same throughout the solution
