At a fixed temperature, equal moles of N2 (g) and F2 (g) are mixed in a constant pressure container (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 3.30 L, determine the volume of the container after the N2 (g) and F2 (g) have reacted to completion.The final volume will be ?
