Unformatted text preview: KE=(1/2)mv^2 lighter particles will arc less than heavier particles Extensive Property: depends on the amount of sample i.e. Mass Intensive Property: independent of amount of sample i.e. Density=mass/unit vol mole= 6.022142 x 10^23 1 mole is the amount of pure substance (i.e. atoms, molecules) that contains the same number of particles as the amount of atoms in exactly 12.0 grams of the carbon 12 isotope Atomic Mass unit (amu)=1/12 the mass of a carbon 12 atom 1 amu=1.661 x 10^(-24)g...
