The standard enthalpy of combustion for methane is -890 kJ/mol.
16.05g/mol
Methane has the formula CH4. So its molecular weight is 12 + 4 = 16. Is that what you mean?
Atomic weight of hydrogen is 1,008. Atomic weight of carbon is 12,011. Atomic weight of chlorine is 35,45. The sum is the molar mass of CHCl3: 119,369 g.
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 standard enthalpy of combustion for methane is -890 kJ/mol.

The atomic (molecular) weight of a substance is its molar mass.
The molar mass of CaCN2 = 80.1021 g/mol
Methane has the formula CH4. So its molecular weight is 12 + 4 = 16. Is that what you mean?
petrolium ether is a mixture of pentane and hexane so has no molar mass
To get the molar mass of copper sulfate (CuSO4) Add the molar masses (atomic weight) of each element of the compound together, this will give you the molar mass of the compound. In This case 159.6086 g/mol
The problem for nitric acid (HNO3). Molar mass would be 63.02g/mol
Atomic weight of hydrogen is 1,008. Atomic weight of carbon is 12,011. Atomic weight of chlorine is 35,45. The sum is the molar mass of CHCl3: 119,369 g.
The molar heat of combustion of methane (890 kJ/mol) is higher than that of water gas (525 kJ/mol)
133.341g/mole
