$C_{2}$

Step 1

To find the mass of $1$ mole of $C_{2}$ look up the atomic mass of each element and multiply it by the number of atoms contained in each element in the molecule.

mass of $1$ mole of $C_{2}$ $=$ $2 (mass of C)$

Step 2

Fill in the atomic masses from the periodic table.

mass of $1$ mole of $C_{2}$ $=$ $2 (12.01000022)$

Step 3

Multiply $2$ by $12.01000022$ .

mass of $1$ mole of $C_{2} = 24.02000045 g$
