Ответ:
6.0055 grams of Carbon
Explanation:
If you look in the periodic table at carbon you can see the atomic molecular mass of 12.011 or something around 12. This number also represents the number of grams in one mole of a substance. So in this case, there are 12ish grams in one mole of carbon atoms. 0.5 moles is just half of a mole. So, 12 grams for one mole divided by 2 would be around 6 grams of carbon atoms for half a mole (or 6.0055 grams considering that one mole is 12.011 grams of carbon atoms)
