calculate the mass in grams of carbon needed to produce 160 grams of CO2 burning. C + O2 -> CO2
mol wt of CO2 = 12 + 32 = 44
160g = 3.64 moles
3.64 moles of C = 3.64 * 12g = 43.63g
Use more precise weights if needed.
Where is the 12g coming from?
To calculate the mass of carbon needed to produce 160 grams of CO2, we need to find the molar ratio between carbon and CO2 in the given chemical equation.
The balanced equation is:
C + O2 -> CO2
According to the equation, for every 1 mole of carbon burned, 1 mole of CO2 is produced. The molar mass of carbon is approximately 12.01 g/mol, and the molar mass of CO2 is approximately 44.01 g/mol.
Now, let's calculate the number of moles of CO2 produced:
Mass of CO2 = 160 grams
Molar mass of CO2 = 44.01 g/mol
Number of moles of CO2 = Mass of CO2 / Molar mass of CO2
= 160 g / 44.01 g/mol
≈ 3.636 moles of CO2
Since the molar ratio between carbon and CO2 is 1:1, the number of moles of carbon needed is also 3.636 moles.
Now, let's calculate the mass of carbon needed:
Mass of carbon = Number of moles of carbon x Molar mass of carbon
= 3.636 moles x 12.01 g/mol
≈ 43.39 grams
Therefore, approximately 43.39 grams of carbon are needed to produce 160 grams of CO2 when burned.
To calculate the mass of carbon needed to produce 160 grams of CO2, we need to consider the balanced chemical equation and the molar masses of carbon and CO2.
The balanced chemical equation is:
C + O2 -> CO2
From the equation, we can see that 1 mole of carbon reacts with 1 mole of O2 to produce 1 mole of CO2.
The molar mass of carbon (C) is approximately 12.01 grams per mole, and the molar mass of CO2 is approximately 44.01 grams per mole.
First, let's calculate the number of moles of CO2 produced:
moles of CO2 = mass of CO2 / molar mass of CO2
moles of CO2 = 160 grams / 44.01 grams per mole
moles of CO2 ≈ 3.63 moles
Since the balanced equation tells us that 1 mole of carbon produces 1 mole of CO2, we know that the number of moles of carbon needed is also 3.63 moles.
Now, let's calculate the mass of carbon needed:
mass of carbon = moles of carbon * molar mass of carbon
mass of carbon = 3.63 moles * 12.01 grams per mole
mass of carbon ≈ 43.72 grams
Therefore, approximately 43.72 grams of carbon are needed to produce 160 grams of CO2 burning.
