What is Molecular Mass?
Molecular mass, also known as molecular weight, is the sum of the atomic masses of all the atoms in a molecule. It is typically expressed in atomic mass units (amu) or grams per mole (g mol). For ethane (C2H6), the molecular mass is calculated by contribute the atomic masses of two carbon atoms and six hydrogen atoms.
Calculating the C2H6 Molecular Mass
To forecast the C2H6 molecular mass, follow these steps:
- Identify the nuclear masses of carbon and hydrogen (H). The nuclear mass of carbon is approximately 12. 01 amu, and the nuclear mass of hydrogen is about 1. 008 amu.
- Multiply the atomic mass of carbon by the figure of carbon atoms in the molecule. For ethane, there are two carbon atoms, so the total mass give by carbon is 2 12. 01 amu 24. 02 amu.
- Multiply the nuclear mass of hydrogen by the routine of hydrogen atoms in the molecule. For ethane, there are six hydrogen atoms, so the total mass lend by hydrogen is 6 1. 008 amu 6. 048 amu.
- Add the masses contributed by carbon and hydrogen to get the full molecular mass of ethane. 24. 02 amu 6. 048 amu 30. 068 amu.
Therefore, the C2H6 molecular mass is about 30. 068 amu or 30. 068 g mol.
Note: The atomic masses used in this calculation are standard values and may vary slimly depend on the source. Always refer to the most late and accurate values for precise calculations.
