= Ideal gas Law= The ideal gas law states the mathematical relationship of pressure (P) volume (V) and temperature (T) the gas constant (R) and the number of moles of a gas (n): PV=nRT

PV= nRT P= Pressure V= Volume n= Number of moles R= Ideal gas constant T= Temperature

PV nRT R= -- = --- nT nT

__Example:__ V= 6L P= 4 atm R= .0821 42g N2 T=? (4atm)(6L)=(1.50 mol)(.0821atm x L(mol x K)) (T) 42g N2 (1 mol N2) = 1.50 mol 28.02 g N2 (4atm)(6L)

(1.50mol)(.0821 atm/L ) = T = 194.88 K
