step 1
choose
choose
multiply all coefficients by an integer if necessary to get a smallest whole number ratio
divide each molar amount by smallest of the molar amounts
derive number of moles of each element using the molar mass of the element
choose
step 2
step 3

Explanation:

Step1: Derive number of moles of each element using the molar mass of the element

This is the first step as shown in the diagram where mass of atoms (for A and X) is divided by molar mass to get moles of atoms.

Step2: Divide each molar amount by smallest of the molar amounts

This step is represented by "Divide by lowest number of moles" in the diagram.

Step3: Multiply all coefficients by an integer if necessary to get a smallest whole number ratio

This corresponds to "Convert ratio to lowest whole number" in the diagram.

Answer:

Step 1: Derive number of moles of each element using the molar mass of the element; Step 2: Divide each molar amount by smallest of the molar amounts; Step 3: Multiply all coefficients by an integer if necessary to get a smallest whole number ratio.
