Answer:
5 moles of oxygen occupy 120 dm³ volume.
Step-by-step explanation:
Given data:
Number of moles = 5 mol
Volume of gas = ?
Solution:
In question it is given gas is at room temperature and pressure.
One mole of any gas at room room temperature and pressure occupy volume of 24 dm³. Thus,
5 mole of gas occupy volume of,
5 mol × 24 dm³/1 mol
120 dm³
5 moles of oxygen occupy 120 dm³ volume.
