Gay-Lussac's Law of combining volumes of gases
states that at constant temperature and pressure, the volumes of gaseous reactants and products can be expressed as ratios of small whole numbers
Avogadro's law
states that, under the same condition of temperature and pressure, equal volumes of all gases contain the same number of mulecules
n
amount of gas in moles
K
ion symbol
standard molar volume of a gas
the volume occupied by one mole of a gas at STP
standard molar volume of gas
1 mol of gas occupies 22.4 L
ideal gas law
law that states the math relationship of pressure (P), volume (V), temperature (T), the gas constant (R=0.0821), and the number of moles of a gas (n); PV=nRT.
