For oxygen it is You can always do this with the last part of this type problem. Glucose, C6H12O6, is the second example.

Empirical Formula This lesson will cover how to start with an empirical formula and determine the chemical formula. There are several steps to get to the empirical formula.
I'm going to percent composition chemistry it into two halves. In the first half, you learn how to determine the percent of elements in a compound. In the second part, you learn how to take those percentages and determine the empirical formula.
First though, you need to understand percent composition chemistry I mean when I say 'empirical formula. The chemical formula, on the other hand, is the shorthand way of writing a substance by using chemical symbols and number subscripts with the exact numbers of atoms.

It's like saying the word family. I can tell you that my family consists of a mother, father and some kids. For one percent composition chemistry,the penny had no copper in it due to the expense of the World War II.
It was just zinc coated steel. The copper coats the outside of the penny while the inner portion percent composition chemistry zinc. The percent percent composition chemistry of a penny may actually affect health, particularly the health of small children and pets. Since the newer pennies are made mainly of zinc instead of copper, they are a danger to a child's health if ingested.

Zinc is very susceptible to acid. If the thin copper percent composition chemistry is scratched and the hydrochloric acid present in the stomach comes into contact with the zinc core it could cause ulcers, anemia, kidney and liver damage, or even death in severe cases.

Of course, the more pennies swallowed, the more danger of an overdose of zinc. The more acidic the environment, the more zinc percent composition chemistry be released in less time.
In this kind of situation, time is of the essence. The faster the penny is removed, the less zinc is absorbed.
Percent Composition Formula
Below is a picture of a scratched penny before and after it had been submerged in lemon percent composition chemistry. As you can see, the copper is vastly unharmed by the lemon juice.
That's why pennies made before with mainly copper except the penny are relatively safe to swallow. Chances are they would pass through the digestive system naturally before any percent composition chemistry could be done.
