If 4.00 moles of O2 occupies a volume of 5.0 L at a particular temperature and pressure, what volume will 3.00 moles of oxygen gas occupy under the same condition?

Volume occupied by 3.00 moles of oxygen gas under the same condition is 3.75 L.

Explanation:

Given: = 4.00 moles,           = 5.0 L

= 3.00 moles,                 = ?

Formula used is as follows.

Substitute the values into above formula as follows.

Thus, we can conclude that volume occupied by 3.00 moles of oxygen gas under the same condition is 3.75 L.
