Mr. Andersen shows you how to convert moles to grams and moles to molecules.

Carry on learning about using moles in this part 2 of 3 parts. Avogradro’s number describes what is known as 1 mole, or 12 g of carbon atoms. This is used in chemical calculations. For any element, the relative atomic mass is the weight...

Watch the final part of the 'using moles' videos, to complete your understanding of the chemical calculations topic. Avogadro’s number describes what is known as 1 mole, or 12 g of carbon atoms. This is used in chemical calculations. For...

The mole is an important concept to understand in chemistry and being able to convert the mole to different units like grams, molecules, ions, atoms or liters is equally important. In this video, we cover the different conversion factors...

This video is on moles and how to convert between grams and moles. The speaker explains what a mole is, its significance in measuring chemical amounts, and the use of Avogadro's constant in determining the number of atoms or molecules in...

This video will explain the concept of a mole and how to convert between moles, grams, and atoms.

Learn the basics about Avogadro's Number, as a part of chemical calculations. Avogadro’s Number or the Avogadro Constant is 6.02 X 1023 Mol-1. It is the number of atoms per mole of the carbon-12 isotope. For atoms, the mass of Avogadro’s...

Learn the basics about using moles. This is part 1 of 3 parts, teaching you about using moles, as a part of the chemical calculations topic. Avogadro’s number describes what is known as 1 mole, or 12 g of carbon atoms. This is used in...

Learn the basics about Avogadro's number - The Mole. What is Avogrado's number? Why is it called like that and what relation does it have to the mole? Find more in this video!

Do you want to know how to calculate the volume of gases? This chemistry video will show you how to do it with simple real world examples. If you know two of these three, you can work out the third: mass in grams, number of moles and...

This video covers concentrations in moles per decimeter cubed, explaining the concept of concentration, how to calculate concentration using mass and volume, and why moles are useful in chemistry. The video also covers how to convert...

This video covers the term 'mole', explains 'Avogadros constant', and runs through examples of the sort of calculations you might have to do with moles.

Yes, I know moles are adorable furry creatures. This is a different kind of mole! A numerical mole. And we need to understand them to be able to make predictions about reactions. Let Professor Dave take you through the finer points.

Molar mass is the mass of 1 mole of a substance. The molar mass of elements can be found on the periodic table and the molar mass of compounds can be found by adding together the molar masses of the elements present in the compound....

Learn how to easily and accurately make a solution and calculate the solution concentration.

Mr. Andersen explains the concept of a limiting reactant (or a limiting reagent) in a chemical reaction. He also shows you how to calculate the limiting reactant and the percent yield in a chemical reaction.

Carry on learning about using moles in this part 2 of 3 parts. Avogradro’s number describes what is known as 1 mole, or 12 g of carbon atoms. This is used in chemical calculations. For any element, the relative atomic mass is the weight...

Watch the final part of the 'using moles' videos, to complete your understanding of the chemical calculations topic. Avogadro’s number describes what is known as 1 mole, or 12 g of carbon atoms. This is used in chemical calculations. For...

The video is a lecture on titration calculations. The video is divided into two parts, with the first part focusing on concentration and molar concentration. The professor explains the concept of concentration and how it is calculated...

We know that concentration is typically expressed with molarity, which is moles per liter. But how do we know how many moles of solute are present in solution when an ionic solid dissolves in water? It's not so simple because these will...

The video explains how to use the masses of reactants and products in a chemical reaction to calculate the balancing numbers in a symbol equation. Two examples are provided to illustrate the process, and the concept of limiting reactants...

If we can use the ideal gas law to find the molar mass of a gas and therefore identify the gas, what can we do with the density of a gas? Well, pretty much the same thing, it just involves one extra calculation, so let's give it a try!

How do we know how many atoms of each element are in a particular compound? Through clever experiments! Here let's practice using percent mass information to get the empirical and molecular formulas of a particular compound.

What the heck is gravimetric analysis? Well let's say we want to know how much of a substance is in some mixture. We could toss it in solution and cause it to form a precipitate with some other ion in solution. We can measure the mass of...
