ideal gas law M P RTEnRT n n is the number of moles of gas present, and r is universal gas constant. R=8.31J/mol.k)=0.082atm·L/(mol·K) Another form of ideal gas law is: pV= NT Nis total number of molecules in the sample k is called Boltzmann constant, which is defined as r 831J/mol K k 1.38×10-23J/K N.6.02×1023/mol
