Final answer:
To find the number of moles of oxygen atoms in 1.34 × 10¹⁷ molecules of ozone, first calculate the moles of ozone and then multiply by 3, as each ozone molecule contains three oxygen atoms. The answer is 0.6675 mol of oxygen atoms.
Step-by-step explanation:
The question involves calculating the number of moles of oxygen atoms in a given number of molecules of ozone (O₃). Given that there are 1.34 × 10¹⁷ molecules of ozone in the sample and that each ozone molecule contains three oxygen atoms, we can find the total number of oxygen atoms present. First, we need to convert the number of ozone molecules to moles using Avogadro's number, which is 6.022 × 10¹⁺ molecules per mole.
1.34 × 10¹⁷ molecules O₃ × (1 mol O₃ / 6.022 × 10¹⁺ molecules) = 0.2225 mol O₃
Since each molecule of O₃ contains 3 atoms of oxygen, the total number of moles of oxygen atoms is:
0.2225 mol O₃ × (3 atoms O / 1 molecule O₃) = 0.6675 mol O
Therefore, the air sample contains 0.6675 mol of oxygen atoms.
