Answer:
I’m not sure if this is right but, 3 moles of oxygen at STP will occupy a volume of 3×22. 4=67. 2 L.
Explanation:
The standard temperature and pressure conditions have a pressure of 1-mole and a volume of 22.4 L. At STP, 3.20 moles of gas will have a volume of 72 L.
The ideal gas equation relates the volume to the moles of the substance. At STP conditions it is known that 1 mole contains 22.4 L.
Given,
Moles of gas = 3.20 moles
1 mole gas at STP = 22.4 L
The volume at 3.20 moles,
= 3.20 × 22.4
= 72 L
Therefore, 72 L is the volume at 3.20 moles.
