Problem

Under certain conditions sodium can react with oxygen to form sodium oxide according to the reaction: 4 Na(s) + O2(g) → 2 Na2O(s)

A flask contains the amount of oxygen represented by the diagram below.
A collection of three molecules, each consisting of two red spheres combined.

Which image below best represents the amount of sodium required to completely react with all of the oxygen in the flask according to the equation?
Four images: a, b, c, and d. Image a depicts four purple spheres. Image b depicts eight purple spheres. Image c depicts twelve purple spheres. Image d depicts six purple spheres.
