Responder

The value of Avogadro's number is \( 6.02 \times 10^{23} \).

Solución

Avogadro's number is a fundamental constant in chemistry that represents the number of atoms, molecules, or particles in one mole of a substance. The correct value of Avogadro's number is: b \( 6.02 \times 10^{23} \) This means that there are approximately \( 6.02 \times 10^{23} \) entities (atoms, molecules, etc.) in one mole of any substance.

Extra Insights

Avogadro's number, which is approximately \( 6.02 \times 10^{23} \), is a fundamental constant in chemistry that defines the number of atoms, molecules, or particles in one mole of a substance. This number helps scientists bridge the gap between the atomic scale and the macroscopic world, allowing us to count particles by weighing them! In practical terms, Avogadro's number is vital in stoichiometry, where it helps chemists figure out how much of each reactant is needed to produce a desired amount of product in chemical reactions. For instance, if you know how many moles of a reactant you start with, you can use Avogadro's number to determine the total number of molecules involved—making it easier to measure and mix your ingredients accurately!
