Interpretation: The volume of oxygen that is required to completely burn
Concept introduction: For ideal gases at STP condition the volume occupied by one mole of it is 22.4L.
The expression for moles is as follows:
Answer to Problem 119A
The volume of oxygen required to completely burn
Explanation of Solution
The given amount of methanol, 36.5L is
The molar mass of methanol is
Substitute
From the equation,
For 2 moles of methanol, about 3 moles of oxygen is required.
Therefore, for one mole of methanol,
So,
The number of moles of oxygen required to burn
One mole of an ideal gas occupies a volume of about
So,
Therefore, the volume of oxygen required to completely burn
