$C O_{2}$

Step 1

To find the mass of $1$ mole of $C O_{2}$ 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 $C O_{2}$ $=$ $(mass of C)$ + $2 (mass of O)$

Step 2

Fill in the atomic masses from the periodic table.

mass of $1$ mole of $C O_{2}$ $=$ $(12.01000022)$ + $2 (16)$

Step 3

Simplify the result.

Step 3.1

Multiply $2$ by $16$ .

mass of $1$ mole of $C O_{2} = 12.01000022 + 32 g$

Step 3.2

Add $12.01000022$ and $32$ .

mass of $1$ mole of $C O_{2} = 44.01000022 g$
