If you have 24 grams of carbon (atomic mass = 12 g/mol), how many moles of carbon do you have?

• A. 2 moles
• B. 24 moles
• C. 12 moles
• D. 0.5 moles

Answer: (A)

Verified step by step guidance

1. Identify the given information: mass of carbon = 24 grams, atomic mass of carbon = 12 g/mol.
2. Recall the formula to convert mass to moles: \(\text{moles} = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}}\).
3. Substitute the given values into the formula: \(\text{moles} = \frac{24}{12}\).
4. Perform the division to find the number of moles of carbon.
5. Interpret the result to select the correct answer from the given options.
