We’re going to look at what are the changes and some state variables, mainly enthalpy, entropy and Gibbs free energy, when we mix ideal gases, or as it turns out, liquids that form ideal solutions. So we’re going to just… Continue Reading
Molarity is just another word for concentration. The formula for molarity is equal to the moles of your solute, divided by the liters of your solution. Now molarity can be used as a conversion factor because it has two different… Continue Reading

Text slide: TROUBLESHOOTING SOUND PROBLEMS If you encounter any sound problems try the following solutions. You can determine whether or not the microphones are set to mute on the Touch Panel. To this go to the Bottom of the Touch… Continue Reading
Welcome to Solution Stoichiometry! Solution stoichiometry is concerned with reactions that are aqueous, or, in other words, reactions that take place in water. And this tutorial assumes you have an acquaintance with basic stoichiometry. If you are not acquainted with… Continue Reading
We’re focusing on an example of solution stoichiometry. So our example states, according to the label on a bottle of concentrated hydrochloric acid, the contents are 36% HCl by mass and have a density of 1.18 grams per milliliter. We’re… Continue Reading
