How many atoms are in 2 moles of oxygen gas (O2)?
Correct Answer: 1.2044 x 10^24 atoms
- Step 1: Understand that 1 mole of any substance contains Avogadro's number of molecules, which is approximately 6.022 x 10^23.
- Step 2: Recognize that oxygen gas (O2) is made up of 2 oxygen atoms in each molecule.
- Step 3: Calculate the number of molecules in 2 moles of O2 by multiplying the number of moles (2) by Avogadro's number (6.022 x 10^23).
- Step 4: Multiply the number of molecules (from Step 3) by 2 to find the total number of oxygen atoms, since each molecule of O2 has 2 atoms.
- Moles and Avogadro's Number – Understanding the relationship between moles, molecules, and atoms using Avogadro's number.
- Molecular Composition – Recognizing that each molecule of O2 consists of 2 oxygen atoms.
