Understanding the Mole Concept
Before diving into project ideas, it's essential to grasp the basics of the mole concept. A mole is a unit in chemistry that represents a specific number of particles, usually atoms or molecules. One mole is equivalent to approximately \(6.022 \times 10^{23}\) particles, a value known as Avogadro's number. This concept allows chemists to quantify substances in a measurable way, making it easier to communicate and compute chemical reactions.
