The ideal gas law PV=nRT relates pressure P, volume V,
temperature T, and number of moles of a gas, n. The gas constant R
equals 0.08206 L⋅atm/(K⋅mol) or 8.3145 J/(K⋅mol). The equation can
be rearranged as follows to solve for n: n=PVRT This equation is
useful when dealing with gaseous reactions because stoichiometric
calculations involve mole ratios.
