The chemical name for molecular formula C3H8 is propane. Propane has a weight of 44.10 grams per mole. Carbon (C) has a weight of 12.01 grams per mole. 1 mole of propane contains 3 moles of carbon. Therefore 81.70 percent by mass of propane is C.
Taking the (approximate) values of the molar masses of carbon (~12g) and hydrogen (~1g):
Methane (CH4) = 12*1 + 1*4 = 16g
So the total mass of carbon in methane is a simple ratio, you could call it the contribution in mass of carbon in methane:
%C = (12/16)*100 = 75%
MrCH4 = 16 grams/mole (The Molecular Mass of Methane)
16 grams/mole = ArC + ArH (to find the relative atomic masses of each)
= 12g + 4g
Therefore:
(12g/16g) x 100 = 75 %the relative Atomic Mass of Carbon / Total mass of MethaneSo 75 % of Methane is Carbon
62.1%
atomic mass of Carbon =12.01g
formula mass 58.09g

carbon dioxide contains about 27.27% carbon.
The reaction isC3H8 + 5O2 ----> 3CO2 + 4H2O100g of propane is approx 2.27 moles.From the equation above, we see that the ratio of C3H8 to CO2 is 1:3, therefore the number of moles of CO2 which form is approx 6.82.This relates to a mass of 300g of CO2
Carbon cannot be stored in a specific area of the ocean, but the mass percent is 0.0028%
Propane is a compound.
If you think to propane (C3H8): carbon - 81,7 % and hydrogen - 17,3 %.
Carbon dioxide is CO2 and has a molar mass of 44g whereas propane is C3H8 and has a molar mass of 44g as well. Therefore, both are of equal mass
The percentage of carbon is 71,58 %.
27.3
carbon dioxide contains about 27.27% carbon.
C10H14O is called carvone or thymol. It has a total molar mass of 150.22 grams per mole, of which carbon is 79.96 percent by mass.
62.1%
Carbon has a atomic mass of 12.So its percentage is 75%
Propsilane as propane C3H8 , carbon is replaced by Silicon.
No, propane is an organic compound containing carbon and hydrogen.
The reaction isC3H8 + 5O2 ----> 3CO2 + 4H2O100g of propane is approx 2.27 moles.From the equation above, we see that the ratio of C3H8 to CO2 is 1:3, therefore the number of moles of CO2 which form is approx 6.82.This relates to a mass of 300g of CO2
In terms of proportion of molecules that are carbon, 33% (formula: CO2 which means that there are 2 oxygens and 1 carbon). If you mean in terms of mass, then carbon is 27.27% of the molecule (Two oxygens at a molecular mass of 16 each, and one carbon at a molecular mass of 12) by mass.
