How many items are there in a mole?
It is widely known that mole is the unit of measurement used to measure the number of things, usually atoms or molecules. It is important to know that one mole of something is equal to 6.0221415Ã—10²³ of it. It is extremely important to know that different molecules and atoms do not have the same mass. This is the main reason one mole of one thing does not weigh the same as one mole of something else. The main idea is that a mole is simply a unit of the number of things.
