Calculate Molar Mass Of Thiophene.
The Correct Answer and Explanation is :
To calculate the molar mass of thiophene (C₄H₄S), we need to sum up the atomic masses of all the atoms in the molecule.
Step-by-Step Calculation:
- Identify the elements in thiophene:
- Carbon (C)
- Hydrogen (H)
- Sulfur (S)
- Find the atomic masses of these elements:
- Carbon (C) has an atomic mass of approximately 12.01 g/mol.
- Hydrogen (H) has an atomic mass of approximately 1.008 g/mol.
- Sulfur (S) has an atomic mass of approximately 32.07 g/mol.
- Calculate the molar mass:
Thiophene has the molecular formula C₄H₄S. This means it contains:
- 4 carbon (C) atoms
- 4 hydrogen (H) atoms
- 1 sulfur (S) atom Now, multiply the number of atoms of each element by its atomic mass:
[
\text{Molar mass of C₄H₄S} = (4 \times 12.01 \, \text{g/mol}) + (4 \times 1.008 \, \text{g/mol}) + (1 \times 32.07 \, \text{g/mol})
]
[
\text{Molar mass of C₄H₄S} = 48.04 \, \text{g/mol} + 4.032 \, \text{g/mol} + 32.07 \, \text{g/mol}
]
[
\text{Molar mass of C₄H₄S} = 84.142 \, \text{g/mol}
]
Thus, the molar mass of thiophene (C₄H₄S) is 84.14 g/mol.
Explanation:
Molar mass, also known as molecular weight, refers to the mass of one mole of a substance. To calculate the molar mass of a compound, we need to know the atomic masses of the elements involved. The molar mass is the sum of the masses of all the atoms in the compound. Thiophene is an aromatic compound with a sulfur atom in place of one of the carbons in the benzene ring. The calculation involves simple multiplication and addition based on the molecular formula.
I will generate the image for the structure of thiophene now.
Here is the image showing the molecular structure of thiophene (C₄H₄S). It illustrates the arrangement of the atoms, including the sulfur atom in the center of the five-membered ring formed by carbon atoms, with hydrogen atoms attached. This should give a clear view of the compound’s structure. Let me know if you’d like further details!
