What Is the Molar Mass of Acetylene?
Answer – The molar mass of C₂H₂, also known as ethyne or acetylene, is approximately 26 grams per mole.
Explanation:
The molar mass is calculated by adding up the atomic masses of each atom in the compound.
In the case of C₂H₂, there are two carbon atoms and two hydrogen atoms. The atomic mass of carbon is approximately 12.01 grams per mole, and the atomic mass of hydrogen is approximately 1.01 grams per mole.
To calculate the molar mass of C₂H₂:
- Multiply the atomic mass of carbon (12.01) by the number of carbon atoms (2): 12.01 x 2 = 24.02 grams per mole
- Multiply the atomic mass of hydrogen (1.01) by the number of hydrogen atoms (2): 1.01 x 2 = 2.02 grams per mole
- Add the results together: 24.02 + 2.02 = 26.04 grams per mole.
