What else can I help you with?
How the you use the percent composition in every day?
You can use percent composition to see how much much flour contributes to the mass of an overall cake. You can see how much kool aid powder is in a given amount of kool aid drink, in percentage. Percentage composition can be used for virtually anything that has a mixture of things. So you don't always have to think percentage composition refers to chemical compounds, such as H2O or KMnO4.

What do chemical formulas tell you the number of?
A chemical formula tells you the number of each type of atom in the molecule or structure.
What does a compound formula tell you?
A compound formula, or molecular formula, tells you about the chemical composition of the substance in terms of the number of atoms of that element that are present. From there, the empirical formula may also be derived by simplifying the molecular formula, as well as its structural formula.
What does percent composition tell you about molecules?
It tells you how much of a molecule is made up of each element. - APEX
What information does the percent composition in an atom in a molecule give?
The relative amount of mass an atom contributes to a molecule

What is the percent composition of Carbon in heptane C7H16 12 percent 68 percent 19 percent or 84 percent?
The percent composition of Carbon in heptane (C7H16) is 84 percent. This can be calculated by dividing the total number of Carbon atoms in the molecule by the total number of atoms and then multiplying by 100 to get the percentage.
