Question

Avogadro’s number was calculated by determining the number of atoms in:

Option 1: 12.00 g of carbon-12
Option 2: 14.00 g of carbon-12
Option 3: 12.00 g of oxygen
Option 4: 14.00 g of oxygen

Answer 1

Avogadro's number was calculated based on the mass of carbon-12 and it is used to convert moles into particles.

Step-by-step explanation:

The number of atoms in a mole is determined by Avogadro's number, which was calculated based on the mass of a specific isotope of carbon. The answer to your question is Option 1: 12.00 g of carbon-12. This is because exactly 12 grams of carbon-12 contains exactly a mole of carbon atoms. Avogadro's number is approximately 6.022 x 10^23 and it is used to convert the number of moles of a substance into the number of particles.
