Questions & Answers

Q: What is the difference between a mole and a molecule?

A mole is a counting number used to measure large quantities, while a molecule is a structure made up of connected atoms. They are not the same thing, as a mole is a number and a molecule is a physical entity.

Q: How is a mole written in scientific notation?

A mole is often written as 6.02 × 10^23, which represents 602 hex trillion things. This notation is used to simplify the expression of such a large number.

Q: Can we count molecules?

Yes, molecules can be counted. For example, a dozen molecules would be 12 molecules and a gross of molecules would be 144 molecules. However, it is also possible to have a mole of molecules, which would be an extremely large quantity of 6.02 × 10^23 molecules.

Q: What is a molecule made of?

A molecule is formed when atoms connect to each other. In the case of ethanol, which is the alcohol found in beer and wine, the molecule is made up of carbon, hydrogen, and oxygen atoms connected to each other through bonds.

Summary & Key Takeaways

  • A mole is a counting number used to measure large quantities, such as a dozen or a gross, but with the mole representing 6.02 × 10^23 things.

  • A molecule is formed when atoms connect to each other, creating a structure, such as the ethanol molecule in alcohol.

  • It is possible to count molecules, but a mole of molecules would represent a significantly larger quantity, equivalent to 6.02 × 10^23 molecules.
