For compounds, it's called "molar mass" instead of atomic. You take each individual element (one C, four H) and add each Atomic Mass: e.g. 12.0 + 4(1.01) = 16.04 g/mol
30.06904 g/mol

What is the relative molecular mass of methane?
Methane has four hydrogen atoms attached to a central carbon atom. Their atomic masses are 1 and 12 respectively. The RMM of methane is 4x1+12=16.
Who is lightest Hydrogen molecule or methane molecule?
Hydrogen molecule is the lightest because of its atomic mass being less than any other molecule .i.e 1amu (atomic mass unit). Hence Hydrogen molecule is lighter than Methane molecule.
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.
The mass of an atom usually expressed in atomic mass units is its?
Atomic mass
What is the atomic mass of silver?
The atomic mass (or weight) of silver is 107.8682 amu (atomic mass units)
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.
What is the mass number of methane?
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 formula for methane is CH4 Four moles of methanes would have a mass of?
The molar mass of methane (CH4) is 16 g/mol. Therefore, four moles of methane would have a mass of 64 grams.

Methane has four hydrogen atoms attached to a central carbon atom. Their atomic masses are 1 and 12 respectively. The RMM of methane is 4x1+12=16.
Who is lightest Hydrogen molecule or methane molecule?
Hydrogen molecule is the lightest because of its atomic mass being less than any other molecule .i.e 1amu (atomic mass unit). Hence Hydrogen molecule is lighter than Methane molecule.
What is the atomic number of CH4?
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.
What is the formula weight of methane CH4?
The formula weight of methane (CH4) is calculated by adding the atomic weights of each element in the compound. Carbon has an atomic weight of 12.01, and hydrogen has an atomic weight of 1.01. Therefore, the formula weight of methane is 12.01 + (4 x 1.01) = 16.05 g/mol.
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 bigger the atomic mass or atomic number?
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
