Problem: The following diagram represents a reaction shown going to completion. Each molecule in the diagram represents 0.1 mol, and the volume of the box is 1.0 L.Assuming that all of the molecules are in the gas phase, calculate n, the change in the number of gas molecules that accompanies the reaction.

We're being asked to calculate n, the change in the number of gas molecules that accompanies the reaction.

Given: diagram represents 0.1 mol

A = red

B = blue

5 A2 plus 5 B goes to 4 A2B plus A2 plus B.
