Why do people still use the mole (unit) in chemistry?

Simply speaking, because it's an appropriate unit to use. Let's imagine I wanted to measure the length of a rope. What would be an appropriate length to use? Inches? Centimeters? Feet, maybe? It would really be awkward to express it as 0.000189393 miles, or as 304,800,000 nanometers. read more

If you're just now learning about moles, it might not click as to why this is the best unit for reactions. If you go on to do some work where you're dealing with lots of chemicals, you'll eventually be thankful that someone invented the convention of the mole. read more

To know why chemists use the mole as a preferred unit of measurement in many contexts, it helps to have a firm understanding of what a mole is. One mole is the amount of substance that contains the same number of elementary particles, such as atoms, molecules or ions, present in a 12-gram sample of pure carbon-12. read more
