Methane is a chemical compound so it does not have an atomic number, but it does have a molecular formula, which is written as CH4.
Methane is composed of one carbon atom (atomic number 6) bonded to four hydrogen atoms (atomic number 1). The molar mass of methane is:
4 * 1.0079 + 12.011 = 16.0426 grams per mole.
The Chemical Formula for methane is CH4. The Weight is 16.04276 g/ mol.
To find the atomic weight you take the masses of the elements and add them together. This is how to find Methane (CH4 ).
Carbon =12.011g/mol
Hydrogen=1.00794 g/mol
12.011+(1.00794 x 4)=16.04276 g/mol
Methane is a compound and therefore does not have any atomic number. It is composed of carbon with atomic number 6 and hydrogen with atomic number 1.
16 is the mass number of Methane.
Percentage of hydrogen in methane is 25%. Percentage of hydrogen = mass of hydrogen/mass of methane x 100 mass of hydrogen = 1 x 4= 4 and mass of carbon = 12. Since methane has 4 hydrogen atoms and one carbon atom therefore mass of methane = 16 Percentage of hydrogen = 4/16 x 100 =25
First a balanced chemical equation is needed.CH4 + 2O2 -> CO2 + 2H2OThere is a 1:1 ratio of moles between methane and carbon dioxide so the amount of moles of methane used is the exact number of moles of carbon dioxide yielded.To determine the number of moles of methane we take the amount used and divide by methane's mass which is about 16.04 g/mol.100g/ 16.04g/mol=6.234moles of methane.6.234 moles of methane are used and 6.234 moles of carbon dioxide are produced.
Each molecule of methane contains one carbon atom, as shown by the formula for methane, CH4. Therefore, the number of carbon atoms in one mole of methane is the same as Avogadro's Number, about 6.022 X 1023.
Methane has the formula CH4. So its molecular weight is 12 + 4 = 16. Is that what you mean?
The chemical formula of methane is CH4; if you think to atoms methane has 5 atoms.
When methane burns, the carbon dioxide and water formed, equal the mass of the methane plus the mass of the oxygen.
The mass of reactants is equal to the mass of products.
Percentage of hydrogen in methane is 25%. Percentage of hydrogen = mass of hydrogen/mass of methane x 100 mass of hydrogen = 1 x 4= 4 and mass of carbon = 12. Since methane has 4 hydrogen atoms and one carbon atom therefore mass of methane = 16 Percentage of hydrogen = 4/16 x 100 =25

CH4 is the compound methane. It does NOT have an atomic number. However it has a Relative Molecular Mass (Mr). To calculate its Mr ;- First refer to the Periodic Table for the Atomic Masses of each element present. We have in CH4 ;- 1 x C = 1 x 12 = 12 4 x H = 4 x 1 = 4 12 + 4 = 16 This is the Mr( Relative Molecular Mass ) of methane ; NOT atomic mass.
12.0 + (4.00000... X 1.0) = 16.0, to the justified number of significant digits.
what is the mass in grams of oxygen, is needed to complete combustion of 6 L of methane?

In methane (CH4), carbon is in the 4- oxidation state.
