Question

How many particles are in one mole? A. 6. 022 × 1023 B. 2. 066 × 1023 C. 6. 023 × 1022 D. 3. 026 × 1022.

Answer 1

A.
`6.022` x
`10^(23)`

Step-by-step explanation:

The number of particles in one mole is known as Avogadro's Number. This number is a constant that is based the number of atoms in a sample of Carbon-12. Avogadro's Number is so large that it is always written in scientific notation, which is why the constant is written as 2 products as opposed to 1 number. Moles and Avogadro's number are useful in Stoichiometry or when determining the formula units or mass of a sample.
