Answer:
<em>23.9 grams carbon</em>
Explanation:
One mole of carbon is 6.023 x 10^23 atoms of C.
If we calculate moles, we can use the molar mass of carbon (12 g/mole) to determine mass of 12x10^23 atoms of C.
(12x10^23 atoms of C)/(6.023 x 10^23 atoms of C/mole C)
moles C = 1.992 moles C
(1.992 moles C)*(12 g/mole C) = 23.9 grams carbon
