What is mole in chemistry short answer?
A mole is defined as 6.02214076 × 1023 of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
What do you call a 10th grader taking chemistry?
Sophomole: Anyone in the 10th grade who is taking chemistry.
Why did Avogadro call it a mole?
(c) Avogadro’s number is often the denominator in mathematical equations, so it was given the name the mole to describe its burrowing characteristics. (d) Two different people, Avogadro and Mole discovered the number at the same time, therefore they share its name.
What is a mole of people?
If a human has a volume density of about 1,000 kg/m3 (humans have a little bit lower density than water since we float), this would give a human volume of: The volume of the mole-human population would then be (6.022 x 1023)(0.05 m3) = 3.011 x 1022 m3. The Earth has a total surface area of around 5.1 x 1014 m2.

Do moles eyes?
Moles are small, burrowing mammals. Their eyes are poorly developed, but what they lack in sight, they make up for in their sense of touch. All moles have very sensitive snouts and long, clawed digits that they use to dig tunnels.

- Physics. Physics is a fascinating field, and taking a course in it will vastly improve your understanding of the world around us.
Why is mole important in terms of studying chemistry?
The mole is important because it allows chemists to work with the subatomic world with macro world units and amounts. Atoms, molecules and formula units are very small and very difficult to work with usually. However, the mole allows a chemist to work with amounts large enough to use.
What is a mole in intelligence?
In espionage jargon, a mole is a long-term spy who is recruited before having access to secret intelligence, subsequently managing to get into the target organization. However, it is popularly used to mean any long-term clandestine spy or informant within an organization, government or private.
