Acetone (3CH3COCH3) undergoes combustion in the presence of oxygen to produce carbon dioxide and water: 2C3H6O+9O2→6CO2+6H2OIf you have 8 moles of acetone, calculate the moles of oxygen needed for complete combustion
Question
Acetone (3CH3COCH3) undergoes combustion in the presence of oxygen to produce carbon dioxide and water: 2C3H6O+9O2→6CO2+6H2OIf you have 8 moles of acetone, calculate the moles of oxygen needed for complete combustion
Solution
To calculate the moles of oxygen needed for complete combustion of 8 moles of acetone, we can use the balanced chemical equation provided:
2C3H6O + 9O2 → 6CO2 + 6H2O
From the equation, we can see that for every 2 moles of acetone, we need 9 moles of oxygen.
Therefore, to find the moles of oxygen needed for 8 moles of acetone, we can set up a proportion:
2 moles acetone / 9 moles oxygen = 8 moles acetone / x moles oxygen
Cross-multiplying, we get:
2 * x = 9 * 8
Simplifying, we have:
2x = 72
Dividing both sides by 2, we find:
x = 36
Therefore, 36 moles of oxygen are needed for the complete combustion of 8 moles of acetone.
