Question

Choose all of the statements below that are true about Avogadro's number and the mole:

A) A mole is a counting unit
B) Avogadro's number is to the mole what "12" is to a "dozen" or what "2" is to a "pair"
C) We can use a conversion factor with Avogadro's number in it to determine the number of particles, atoms and/or molecules in a substance of given moles.
D) A mole simply means 6.022 x 10^23 of something (atoms, molecules, particles)
E) Avogadro's number is 6.022

Answer 1

A, B, C, D

Step-by-step explanation:

Avogadro number is a constant at 6.022 x 10^23. The number is equivalent to a mole in Chemistry. It stipulates the number of particles expected in a mole of a substance. This unit of measurement is named after its inventor, Amedeo Avogadro, an Italian scientist.

It is also used to derive the molar mass of a substance. Dalton is used in expressing the mass of a mole of a substance– atomic mass unit (AMU) * Mass Number.
