PC Example 1: What is the percent composition of K in the compound

K2O?

Step 1: Find the mass of each element.

Step 2: Get the total molecular mass by adding the mass of each element.

Step 3: Divide the total mass of each element by the molecular mass and then multiply by 100 to get percent composition.
