Question

What is the molar mass of sulfur dioxide (SO$_2)$?

• A. \( 64 \, \text{g/mol} \)
• B. \( 32 \, \text{g/mol} \)
• C. \( 48 \, \text{g/mol} \)
• D. \( 44 \, \text{g/mol} \)

Hint:

Remember: The molar mass of a compound is the sum of the atomic masses of its constituent elements, multiplied by the number of atoms of each element in the compound.

Answer 1

The Correct Option is A

Step 1: Calculate the molar mass of SO\(_2\)
The molar mass of a compound is the sum of the atomic masses of its elements, with the appropriate number of atoms. - Atomic mass of sulfur (S) = \( 32 \, \text{g/mol} \) - Atomic mass of oxygen (O) = \( 16 \, \text{g/mol} \)
Step 2: Add the atomic masses
For SO\(_2\), there is one sulfur atom and two oxygen atoms: \[ \text{Molar mass of SO}_2 = 32 + 2 \times 16 = 32 + 32 = 64 \, \text{g/mol} \]
Answer:
Therefore, the molar mass of sulfur dioxide (SO\(_2\)) is \( 64 \, \text{g/mol} \). So, the correct answer is option (1).
