How many oxygen atoms does 1 mol of O2 gas contain?A.2B.2 × 16.00C.6.02 × 1023D.2 × (6.02 × 1023)

Break Down the Problem

1. Determine the composition of oxygen gas (O$_2$).
2. Understand Avogadro's number and how it relates to moles.

Relevant Concepts

1. Oxygen gas (O$_2$) is molecular oxygen, which means each molecule contains 2 oxygen atoms.
2. Avogadro's number states that 1 mole of any substance contains $6.02 \times 10^{23}$ entities (atoms, molecules, etc.).

Analysis and Detail

1. Given that 1 mole of O$_2$ gas contains $6.02 \times 10^{23}$ molecules of O$_2$:
   • Each molecule of O$_2$ contains 2 oxygen atoms.
   • Therefore, the total number of oxygen atoms in 1 mole of O$_2$ can be calculated as follows: $\text{Total oxygen atoms} = 2 \times (6.02 \times 10^{23}) = 1.204 \times 10^{24}$

Verify and Summarize

The calculation indicates that 1 mole of O$_2$ gas contains $1.204 \times 10^{24}$ oxygen atoms. This corresponds with option D, where you have $2 \times (6.02 \times 10^{23})$.

Final Answer

The answer is D. $2 \times (6.02 \times 10^{23})$.
