How many carbon atoms are present in 19 molecules of benzene (C6H6)?

• A. 19
• B. 114
• C. 6
• D. 38

Answer: (B)

Verified step by step guidance

1. Identify the molecular formula of benzene, which is \(C_6H_6\). This means each molecule of benzene contains 6 carbon atoms.
2. Determine the number of molecules given, which is 19 molecules of benzene.
3. To find the total number of carbon atoms, multiply the number of carbon atoms per molecule by the number of molecules: \$6 \times 19$.
4. Set up the multiplication expression: \(\text{Total carbon atoms} = 6 \times 19\).
5. Calculate the product to find the total number of carbon atoms in 19 molecules of benzene.
