"atomic weight" is always on the x-axis of the mass spectrum graph.
the x and y is the name of the axis, you need to label the axis on a graph as X and Y.X is the the line that goes horizontally and y is the one that goes in a portrait way.the way to remember is .if you cross your hand to make the X letter one hand goes across the other therefore the axis x is the line that is going across.
The x-axis comes first. because x comes before y.
