Find the Mass Percentages CO_2

$C O_{2}$

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.

Multiply $2$ by $16$ .

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

Add $12.01000022$ and $32$ .

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

Step 4

Find the mass percentage of $C$ .

The mass composition percentage is the mass of $C$ divided by the mass of the entire molecule converted to a percentage.

Mass percentage of $C = \frac{12.01}{44.01000022} \cdot 100$

Divide $12.01$ by $44.01000022$ .

$0.27289252 \cdot 100$

Multiply $0.27289252$ by $100$ .

$27.2892523$

Set the number as a percent.

Mass percentage of $C = 27.2892523 %$

Step 5

Find the mass percentage of $O$ .

The mass composition percentage is the mass of $O$ divided by the mass of the entire molecule converted to a percentage.

Mass percentage of $O = \frac{32}{44.01000022} \cdot 100$

Divide $32$ by $44.01000022$ .

$0.72710747 \cdot 100$

Multiply $0.72710747$ by $100$ .

$72.71074717$

Set the number as a percent.

Mass percentage of $O = 72.71074717 %$

Step 6

Find the mass percentage of each element in the molecule.

Mass percentage of $C = 27.2892523 %$

Mass percentage of $O = 72.71074717 %$
