Here's how to calculate the number of moles in a 63.60 g sample of carbon:

1. Find the molar mass of carbon:

* The molar mass of carbon (C) is 12.01 g/mol (you can find this on the periodic table).

2. Use the formula:

* moles = mass / molar mass

3. Plug in the values:

* moles = 63.60 g / 12.01 g/mol

4. Calculate:

* moles = 5.30 mol

Therefore, there are 5.30 moles in a 63.60 g sample of carbon.
