Question
How many oxygen atoms does 1 mol of O2 gas contain?A.2B.2 × 16.00C.6.02 × 1023D.2 × (6.02 × 1023)
Solution
The correct answer is D. 2 × (6.02 × 1023).
Here's the step-by-step explanation:
-
A molecule of O2 gas contains 2 oxygen atoms.
-
1 mole of any substance contains Avogadro's number of that substance, which is 6.02 × 10^23.
-
Therefore, 1 mole of O2 gas would contain 2 × (6.02 × 10^23) oxygen atoms.
