We discuss commonly asked questions about ionic bonding and valence electrons.

Introduction to Thermochemistry and Enthaply

$Mole Fraction Practice Problems Here, we work through two practice problems involving mole fraction. Mole fraction is calculation that is used to determine the concentration of components in a mixture. The number of moles of a certain component is divided by the total number of moles in the mixture. When the numbers are not given in moles, you first have to convert from gams to moles by using the molar mass. This video will be helpful to people taking chemistry classes in both high school and college/university, and also preparing for exams like the AP, A-levels, SAT, O-levels, MCAT, DAT, OAT, IGCSE, ICSE, CBSE, JEE, NEET, and IB.$
