That being said, if you’re pressed for time, you can try it.

Recall this question: , meaning that we need twice as many moles of oxygen as we do methane.

Composition stoichiometry describes the quantitative relationships among elements in compounds.

It can be used to determine the number of atoms present in a collection of molecules and the masses of each.

Percent yield is a way of quantifying the difference between the theoretical yield (the expected value) and the experimental yield.

## How To Solve Mass To Mass Stoichiometry Problems

Using the same reaction yet again, let’s say that you were given a problem like this. In fact, there is an easier way to do this calculation.

Let’s say that we have this equation, which is the combustion of methane. Then I do the same on the right side: one carbon, two hydrogens, and three oxygens. The only way to get that four hydrogens is to double the amount of …and this equation is now balanced.

You’ve probably learned much of this even in a non-AP chemistry class, so bear with me; it’ll get more advanced.

In other words, stoichiometry is the practice of using a chemical reaction equation to predict the results of the reaction. Of course, that means that we need to start with a chemical reaction.

When we look at the two sides of the reaction, we have to make sure that the number of atoms of each element on each side is the same because of the principle of conservation of mass. In this section of the AP Chemistry Crash Course, we’ll start by looking at the basic concepts of stoichiometry, and then we’ll cover five applications for stoichiometry on the AP Chemistry exam.
