Propane is widely usid in liquid form as a fule for barbecue grills and camp stoves for 58.5g of propane, calculate the following quantities. The grams of carbon?
55.8 g C3H8 x (3 moles C/1 mole C3H8) = ??
Substitute atomic mass C and molar mass C3H8 and calculate.
To calculate the grams of carbon in 58.5g of propane, we need to determine the molar mass of propane and the molar mass of carbon.
The chemical formula of propane is C3H8. The molar mass of carbon (C) is approximately 12.01 g/mol.
To find the molar mass of propane, we add the molar masses of carbon and hydrogen.
Molar mass of propane (C3H8) = 3(C) + 8(H) = 3(12.01 g/mol) + 8(1.01 g/mol) = 36.03 g/mol + 8.08 g/mol = 44.11 g/mol
Now, we can calculate the grams of carbon in 58.5g of propane using the ratio of carbon to propane in terms of moles.
Moles of propane = (58.5 g) / (44.11 g/mol) ≈ 1.326 mol
Since there are 3 moles of carbon in 1 mole of propane (as indicated by the chemical formula C3H8), we can calculate the moles of carbon.
Moles of carbon = 3(1.326 mol) = 3.978 mol
Finally, we can convert moles of carbon to grams of carbon using the molar mass of carbon.
Grams of carbon = (3.978 mol) x (12.01 g/mol) ≈ 47.82 g
Therefore, there are approximately 47.82 grams of carbon in 58.5 grams of propane.
To calculate the grams of carbon in 58.5g of propane, we need to determine the percentage of carbon in the propane molecule and then use that percentage to calculate the actual grams of carbon.
The chemical formula of propane is C3H8, which means it contains three carbon atoms (C) and eight hydrogen atoms (H).
To find the percentage of carbon in propane, we need to calculate the molar mass of carbon in the molecule:
Molar mass of carbon = atomic mass of carbon x number of carbon atoms
= 12.01 g/mol x 3
= 36.03 g/mol
Next, we calculate the molar mass of the entire propane molecule:
Molar mass of propane = (molar mass of carbon x number of carbon atoms) + (molar mass of hydrogen x number of hydrogen atoms)
= (36.03 g/mol x 3) + (1.01 g/mol x 8)
= 108.09 g/mol + 8.08 g/mol
= 116.17 g/mol
Now, we can determine the percentage of carbon in propane:
Percentage of carbon = (molar mass of carbon x number of carbon atoms) / molar mass of propane x 100%
= (36.03 g/mol x 3) / 116.17 g/mol x 100%
= 108.09 g / 116.17 g x 100%
= 93.06%
Finally, we can calculate the grams of carbon in 58.5g of propane:
Grams of carbon = percentage of carbon x mass of propane
= 93.06% x 58.5g
= 54.52g
Therefore, there are approximately 54.52 grams of carbon in 58.5g of propane.
