At a fixed temperatureequal molesof n2g and f2g are mixed

Question

At a fixed temperature,equal molesof N₂(g) and F₂(g) are mixed in aconstant pressurecontainer (the volume of the container changes in order to keep the pressure at a constant value). The N₂(g) and F₂(g) are allowed to react, producing NF₃(g):

N₂(g) + 3F₂(g) → 2 NF₃(g)

If the initial volume of the container, before any reaction takes place, is 5.40 L, determine the volume of the container after the N₂ (g) and F₂ (g) have reacted to completion.
