What is Acetylene and Its Chemical Formula?
Acetylene, also known as ethyne, is a hydrocarbon belonging to the alkyne group. Its chemical formula, C₂H₂, indicates it consists of two carbon atoms and two hydrogen atoms. This simple structure makes it a versatile compound used in welding, cutting metals, and synthesizing organic compounds.
How to Calculate the Molar Mass of Acetylene
To find the molar mass of acetylene, follow these steps:
1. Identify Atomic Masses:
- Carbon ©: Approximately 12.01 g/mol.
- Hydrogen (H): Approximately 1.008 g/mol.
2. Multiply by the Number of Atoms:
- Carbon: (2 \times 12.01 = 24.02 \, \text{g/mol}).
- Hydrogen: (2 \times 1.008 = 2.016 \, \text{g/mol}).
3. Add the Results:
- Total molar mass = (24.02 + 2.016 = 26.036 \, \text{g/mol}).
📌 Note: Always use the most accurate atomic masses for precise calculations.
