calculate the amount of carbon dioxide that could produced when the one mole of carbon is burnt in 8gms of dry oxygen
One mole of carbon + 1/4 mole of O2?
C+O2>>.CO2
that tells my you cannot get more than 1/8 mole of CO2.
To calculate the amount of carbon dioxide produced when one mole of carbon is burnt in 8 grams of dry oxygen, we first need to determine the balanced chemical equation for the combustion of carbon.
The balanced equation for the combustion of carbon is as follows:
C + O₂ → CO₂
Based on the equation, we can see that each mole of carbon reacts with one mole of oxygen to produce one mole of carbon dioxide.
Now, to calculate the amount of carbon dioxide produced, we need to determine the number of moles of carbon and oxygen in the given quantities.
- Carbon (C):
Since we have one mole of carbon, the number of moles is already given as 1.
- Oxygen (O₂):
To find the number of moles of oxygen, we need to convert the given mass (8 grams) to moles.
The molar mass of oxygen (O₂) is 32 g/mol (as the molar mass of oxygen gas (O₂) is 32 g/mol).
Now, we can use the formula:
Number of moles = Mass / Molar mass
Number of moles of oxygen (O₂) = 8 g / 32 g/mol = 0.25 mol
From the balanced equation, we know that one mole of carbon reacts with one mole of oxygen, so the amount of carbon dioxide produced will also be 0.25 moles.
Finally, using the formula:
Mass = Number of moles x Molar mass
Mass of carbon dioxide (CO₂) = 0.25 mol x 44 g/mol = 11 grams
Therefore, when one mole of carbon is burnt in 8 grams of dry oxygen, approximately 11 grams of carbon dioxide is produced.
