What is the gram atomic mass of lithium?

An empty fuel tank can still contain and therefore can be even more dangerous than one full of liquid fuel.

Consider the reaction: n2(g) + o2(g) ? 2no(g) kc = 0.10 at 2000oc starting with initial concentrations of 0.040 mol/l of n2 and 0.040 mol/l of o2, calculate the equilibrium concentration of no in mol/l how would this be done?
