Question

What could be better than a dozen $\left(12\right)$ donuts? How about a baker's dozen $\left(13\right)$ of donuts? Another large unit of measurement is known as Avogadro's number $(6.022\times {10}^{23})$.
What is TRUE about Avogadro's number?

• A. Avogadro's number is the number of particles in one mole of any element.
• B. The molar mass of a substance will contain $6.022\times {10}^{23}$ molecules.
• C. There are $6.022\times {10}^{23}g$ of carbon in $12$ mol of $C-12$.
• D. $6.022\times {10}^{23}$ atoms of any element will have the exact same mass regardless of the identity of the element.

Answer 1

Answer: (A)

Avogadro's number is the number of particles in one mole of any element.

Avagadro constant i.e. $6.023\times {10}^{23}$ particles is the number of constituent particles, usually atoms or molecules, that are contained in the amount of substance given by $1mole$.
