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.
What else can I help you with?
What is the atomic mass number of methane?
The atomic mass number of methane (CH4) is the sum of the atomic masses of its constituent elements. Carbon has an atomic mass of approximately 12, and hydrogen has an atomic mass of approximately 1. Adding these together gives a total atomic mass number of 16 for methane.
How many moles of methane are there in 8.02 g of methane?
To find the number of moles of methane in 8.02 g, you need to divide the given mass by the molar mass of methane (16.04 g/mol). 8.02 g / 16.04 g/mol = 0.500 moles of methane
What is the molar mass of methane CH?
The molar mass of methane (CH₄) is approximately 16.04 g/mol.
How many moles are in 0.289 g of methane?
To find the number of moles in 0.289 g of methane, first calculate the molar mass of methane (CH4), which is approximately 16 g/mol. Next, divide the given mass (0.289 g) by the molar mass to obtain the number of moles. Therefore, 0.289 g of methane is equivalent to 0.289 g / 16 g/mol ≈ 0.018 moles of methane.
Percent of hydrogen in 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
What is the atomic mass number of methane?

How many moles of methane are there in 8.02 g of methane?
To find the number of moles of methane in 8.02 g, you need to divide the given mass by the molar mass of methane (16.04 g/mol). 8.02 g / 16.04 g/mol = 0.500 moles of methane
When methane burns carbon dioxide and water are formed The mass of carbon dioxide plus the mass of water equal the mass of the methane plus the mass of OXYGEN?
When methane burns, the carbon dioxide and water formed, equal the mass of the methane plus the mass of the oxygen.
What is the molar mass of methane CH?
The molar mass of methane (CH₄) is approximately 16.04 g/mol.
Why the combined mass of CO2 and H2O produced in the combustion analysis of methane greater than mass of the methane sample being analysed?
The mass of reactants is equal to the mass of products.
How many moles are in 0.289 g of methane?
To find the number of moles in 0.289 g of methane, first calculate the molar mass of methane (CH4), which is approximately 16 g/mol. Next, divide the given mass (0.289 g) by the molar mass to obtain the number of moles. Therefore, 0.289 g of methane is equivalent to 0.289 g / 16 g/mol ≈ 0.018 moles of methane.
Percent of hydrogen in 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
How many atoms of carbon is in methane and molecular mass?
Methane (CH4) contains 1 carbon atom. The molecular mass of methane is approximately 16 g/mol.
The formula for methane is CH4. Four moles of methane would have a mass of how many grams?
To calculate the mass of four moles of methane (CH4), we first need to determine the molar mass of methane. The molar mass of CH4 is the sum of the atomic masses of carbon (12.01 g/mol) and hydrogen (1.008 g/mol) multiplied by the number of atoms in the compound. Therefore, the molar mass of CH4 is 12.01 g/mol + 4(1.008 g/mol) = 16.04 g/mol. To find the mass of four moles of methane, we multiply the molar mass by the number of moles: 16.04 g/mol x 4 mol = 64.16 grams. Therefore, four moles of methane would have a mass of 64.16 grams.
How many molecules in 10 grams of methane?
Find out the percentage of hydrogen in the molar mass of methane. Molar mass of CH4: C = 1 * 12.01 g = 12.01 g H = 4 * 1.01 g = 4.04 g Total = 16.05 g 4.04 g/16.05 g * 100% = 25.171% 0.25171 * 20 g = 5.0342 g There are about 5.03 grams of hydrogen in 20 grams of methane gas.
