Atomic mass unit: 1.00 amu = 1.67 x <math>10^{-27}</math>kg
Avogadro's number: 6.02 x <math>10^{23}</math> particles/mole
Planck's constant: 6.23 x <math>10^{-34} \frac{Joules}{Hertz}</math>
R = 0.0821 <math>\frac{L \cdot atm}{mole \cdot K}</math> or 8.314 <math>\frac{J}{mole \cdot K}</math>
Standard Temperature and Pressure (STP): temperature = 273 K and pressure = 1.00 atm
