This is from my chemistry assignment : 1) You have a tank of N2 gas. If the tank contains 11.65 L of the gas (at STP), how many molecules of N2 are in it?
can someone pls explain how I would answer this and what equation I would use ?

Consider this equilibrium: n29) + o2(g) + 2no(c).nitrogen gas and oxygen gas react when placed in a closed container. as the reaction proceeds towards equilibrium, what happens to the rate of thereverse reaction?
