1. What's the value of the number?

6.522140857 × 10^15

6.022140857 × 10^23

6.022142357 × 10

6.111407 × 10^10

The given answer, 6.022140857 × 10^23, represents a number in scientific notation. In scientific notation, a number is expressed as a decimal number multiplied by a power of 10. The power of 10 indicates the number of places the decimal point has been moved to the right or left. In this case, the number 6.022140857 is multiplied by 10 raised to the power of 23, which means the decimal point has been moved 23 places to the right. Therefore, the value of the number is a very large number, 6.022140857 followed by 23 zeros.

2. What's the name of the man behind the number?

Stefano

Amedeo

Luigi

Andrea

The name of the man behind the number is Amedeo.

Explanation

The name of the man behind the number is Amedeo.

3. Who actually cemented the theory but named it in the honor or Avogadro?

Erwin Schrödinger

Jean Perrin

Richard Feynman

Max Planck

Jean Perrin is the correct answer because he was the one who actually cemented the theory, but named it in the honor of Avogadro. Perrin was a French physicist who conducted experiments on Brownian motion, which provided strong evidence for the existence of atoms and molecules. He also made significant contributions to the understanding of Avogadro's law and the determination of Avogadro's number. Therefore, Perrin's work played a crucial role in solidifying the theory and honoring Avogadro's contributions to the field of chemistry.

6. What's the symbol of Avogadro's number?

Q

L

T

Nt

The symbol for Avogadro's number is "L". Avogadro's number, also known as Avogadro's constant, is a fundamental constant in chemistry and physics that represents the number of particles (atoms, molecules, ions, etc.) in one mole of a substance. The symbol "L" is derived from the Italian word "loschimia," which means chemistry. It is used to represent Avogadro's number in various equations and calculations involving the mole concept.

7. What's the number called in German literature?

Loschmidt Constant

Japhetic Constant

Fokker–Planck Constant

Lanck's Black Body Radiation Constant

The Loschmidt Constant, also known as the Avogadro Constant, is a fundamental constant in physics and chemistry. It represents the number of particles (atoms, molecules, ions) present in one mole of a substance and is often used to convert between the macroscopic and microscopic scales. It is named after the Austrian physicist Johann Loschmidt, who made significant contributions to the understanding of gases and kinetic theory. In German literature, the Loschmidt Constant may be mentioned in the context of scientific discussions or historical references.

10. Do you know the unit of Avogadro's number?

Mol

N

N^-1

Mol^-1

The unit of Avogadro's number is N^-1. This is because Avogadro's number represents the number of particles (atoms, molecules, ions, etc.) in one mole of a substance. The unit N^-1 indicates that it is the reciprocal of Avogadro's number, meaning it represents the number of moles per particle. So, N^-1 is the correct unit for Avogadro's number.
