Final answer:
We cannot determine the number of moles of carbon without additional information.
Step-by-step explanation:
In order to determine the number of moles of carbon, we need to know the number of carbon atoms in the original sample.
From the given options, we don't have enough information to directly calculate the moles of carbon in the sample. We would need additional data such as the mass of the sample or the molar mass of the substance containing carbon.
Therefore, without additional information, we cannot determine the number of moles of carbon in the original sample.
