Problem-Solving Skills: Percentage Composition
If you know the base elements in a mixture, do you know what compound they form? Not always. Sometime the
same three or four elements can combine into many different compounds. Here's a tried and true method for determining what
percentage of each element is in a compound to help you identify it correctly.
