Calculating Molecular Formula from Empirical Formula
 
09:09
We'll learn how to calculate molecular formula for a compound when you are given its empirical formula and its molar mass. In order to do this, you need to figure out what to multiply the empirical formula by to get the molecular formula and the correct molar mass. The multiple can be determined by dividing the molar mass of the compound by the molar mass of the empirical formula.

Find the Empirical Formula Given Percents
 
05:48
If you're given the Percent Composition of a compound, you can find the Empirical Formula for it. I have the shortest method ever to do it, although it's not a "full solution" like your teacher probably asks for. 1. Divide each % by the atomic mass of the element 2. Divide each of THOSE answers by whatever's smallest 3. Adjust these numbers into their lowest whole-number ratio. Check me out: http://www.chemistnate.com

Writing Empirical Formula Practice Problems
 
06:09
We'll practice writing empirical formulas for a whole bunch of molecular formulas. In order to write the empirical formula, you find the largest number you can divide all of the subscripts by, to reduce it as much as possible. You know that you have the empirical formula when your new compound formula cannot be reduced any more. For some formulas, the molecular formula is that same as the empirical formula. Also, it's possible for more than one compound to have the same empirical formula. In fact, that happens quite often.

Empirical Formula and Molecular Formula Introduction
 
08:31
We will talk about what empirical formula and molecular formula are, how they are different, and we'll learn how to write the empirical formula for a compound when you are given the molecular formula. Molecular formulas tell you how many atoms of each element are in a compound, and empirical formulas tell you the simplest or most reduced ratio of elements in a compound. If a compound's molecular formula cannot be reduced any more, then the empirical formula is the same as the molecular formula. Also, many compounds with different molecular formula have the same empirical formula.

Percent Composition By Mass
 
06:58
We'll learn how to calculate percent composition by mass, and we'll work through a number of practice problems. To calculate percent by mass, you need to determine two things: the mass of just the element, and the molar mass of the whole compound. Then, you take the molar mass of just the element and divide it by the molar mass of the whole compound, and multiply by 100%.

How to Calculate Molar Mass Practice Problems
 
13:11
We will learn how to calculate the molar mass of a compound by using its chemical formula. Molar mass is a quantity that is very similar to molecular mass, molecular weight, formula mass, and formula weight. In order to calculate molar mass, we look at the formula to determine how many atoms of each type are in it, and then look at the periodic table to determine the atomic mass of each of the atoms. We will look at compounds containing polyatomic ions, and also hydrate compounds.

Converting Between Grams and Moles

We'll learn how to convert back and forth between grams and moles. For each example, we'll do it two ways. First, a thinking through it approach, that shows how you multiply moles by the molar mass to convert from moles to grams, and how you divide grams by the molar mass to convert from grams to moles. Second, we'll use a conversion factor method where we write units based on molar mass information, and set up fractions to correctly cancel the units.

Binary compounds made of two nonmetals are called covalent or molecular because the elements are held together with covalent bonds, and they make molecules.

Greek prefixes to show the number of atoms of each element, and these are put in front of the element names.
