The balanced equation for the combustion of CH4 is CH4 + 2O2 ==> CO2 + 2H2O4 molecules of CH4 will produce 4 molecules of CO2 and 8 molecules of H2O
How many molecules are in 30 liters of methane (CH4) at STP
None. CH4 is methane. NH3 is ammonia. You have made some kind of error.
Divide 2.52 by molecular mass 16.Then multiply by avagadro constant
nh3-nh3 because they are both polar molecules
No, many do not. For example methane CH4.

It represent a one molecule.CH4 stands for Methane
No, many do not. For example methane CH4.
6 molecules of oxygen are needed to react with 3 methane molecules as one molecule of oxygen ( O2) are needed for methane gas.
The formula for methane is CH4, showing that each molecule contains exactly 5 atoms. Therefore, the number of atoms in 0.650 ml is 5 X 0.650 X Avogadro's Number, or about 1.96 X 1024 atoms, to the justified number of significant digits.
Molecular mass of CH4 = 12.0 + 4(1.0) = 16.0 Amount of CH4 = 64.5/16.0 = 4.03mol 1mol of CH4 contains 6.02 x 1023 molecules (avogadro constant). Therefore 4.03mol of CH4 contains 4.03 x 6.02 x 1023 = 2.43 x 1024 molecules.
Many gases are made of molecules and exist at room temperature. The atmosphere is mainly oxygen and nitrogen, both these have molecules with two atoms. O2 and N2. Then there are small amounts of other gases like carbon dioxide CO2, methane CH4, sulphur dioxide SO2. So there are plenty of molecules.
One mole is equal to 6.022 x 1023 of anything. In this case, we are looking for molecules. So 1 mole=6.022 x 1023 molecules. We have 2.3 moles, so we want to know how many molecules are there. 2.3 mol CH4 x 6.022x1023 molecules CH4 / mol CH4 = 1.38x1024 molecules of CH4
The periodic table lists only elements and not compounds / molecules like CH4.
