D
0.5 moles
0 Comments
Verified step by step guidance1
Identify the given information: mass of carbon = 24 grams, atomic mass of carbon = 12 g/mol.
Recall the formula to convert mass to moles: \(\text{moles} = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}}\).
Substitute the given values into the formula: \(\text{moles} = \frac{24}{12}\).
Perform the division to find the number of moles of carbon.
Interpret the result to select the correct answer from the given options.
