$1$ $m o l$ of carbon has a mass of $12.011$ $g$. So $\frac{1}{2}$ mole $C$ has a mass of about $6$ $g$.

Explanation:

Did you have to remember this? Even though this is a trivial problem, you MIGHT have been asked the mass in grams of half a mole of iron, or antimony, or osmium. You will be issued with a Periodic Table, which will tell you the molar masses of each element.

A follow up question is, "How many $C$ atoms are there in $6$ $g$ of carbon?"
