Step 1
Volumes of Ar and F₂
Answer
At standard conditions (0°C and 100 kPa), one mole of any ideal gas occupies approximately 22.71 litres. For argon, Ar, and fluorine, F₂, we can assert that:
- Volume of 1 mole of Ar = 22.71 litres
- Volume of 1 mole of F₂ = 22.71 litres
Thus, the correct option is (B) 22.71 litres for both gases.
