Hint: The mole is a unit to measure the amount of a substance in chemical terms. A mole is defined as the amount of substance which is equal to the molar mass of that substance.

Carbon is an element in the periodic table with atomic number $6$. It consists of $6$ protons, $6$ electrons and $6$ neutrons. The number of moles is determined by the amount of the substance present in a fixed quantity.
The mole of a substance is defined as the amount of substance present in equal amount to the molecular weight or molar mass of an atom or a molecule. Also a mole is equal to the amount of substance which contains the number of atoms equal to $6.023 \times {10^{23}}$.
The molar mass of a carbon atom is $12amu$. The unit $amu$ stands for atomic mass unit. Thus for convenience of measurement we generally express the mass of the carbon atom is $12g$.
From the above concept of mole we tell that one mole of carbon contains $12g$ of carbon, which is the molar mass of carbon. So the amount of carbon present in $2$ moles of carbon =$2 \times 12{\text{ }}g = 24g$.
Hence $24g$ of carbon is present in $2$ moles of carbon.
Note: The molar mass is also termed as the total mass of one mole of a substance. The molar mass of water molecules is $18g$. So it is obvious that one mole of water contains $18g$ of water. The unit of molar mass is $g/mol$ or $kg/mol$.
