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 atomic number of the nucleus?
The atomic number is the number of protons in a nucleus.
Every element has its own atomic number the atomic number is the number of what?
the atomic number represents the number of protons in an elements atoms
What determines the atomic number of a substance?
The atomic number is the number of protons in the nucleus of an atom, while the atomic mass is the total mass of the nucleus (both protons and neutrons)
Atomic number of an atom is equal to the number of?
The atomic number of an atom is the number of protons in that atom. For example, the atomic number of hydrogen is 1 because one hydrogen atom have one proton.
The atomic number of an element is determined by the number of?
The atomic number of an element is determined by the number of protons within it's nucleus.
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.
What is the atomic weight of one mole CH4?
4
In CH4 - is 4 a catalyst?
CH4 is the chemical formula of methane; 4 is the number of carbon atoms.
What is the weight percent of carbon in CH4?
Carbon has a atomic mass of 12.So its percentage is 75%
How much mass does a ch4 molecule have?
Add atomic masses of each atom.So answer is about 16
Number ammonia molecules in 3.75g of CH4?
To find the number of ammonia molecules in 3.75g of CH4, you first need to convert 3.75g of CH4 to moles using the molar mass. Then, you need to use the mole ratio between CH4 and NH3 to find the number of ammonia molecules in the given amount of CH4. The mole ratio for CH4 to NH3 is 1:3, as 1 molecule of CH4 produces 3 molecules of NH3 in the balanced chemical equation.
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.
How many moles of CH4 are in 200 grams of CH4?
200 g CH4 x 1 mole CH4/16 g = 12.5 moles CH4
