Find the Mass Percentages CH_4O

$C H_{4} O$

Step 1

To find the mass of $1$ mole of $C H_{4} O$ 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 $C H_{4} O$ $=$ $(mass of C)$ + $4 (mass of H)$ + $(mass of O)$

Step 2

Fill in the atomic masses from the periodic table.

mass of $1$ mole of $C H_{4} O$ $=$ $(12.01000022)$ + $4 (1.00999999)$ + $(16)$

Step 3

Simplify the result.

Remove parentheses.

mass of $1$ mole of $C H_{4} O = (12.01000022) + 4 (1.00999999) + 16 g$

Multiply $4$ by $1.00999999$ .

mass of $1$ mole of $C H_{4} O = 12.01000022 + 4.03999996 + 16 g$

Add $12.01000022$ and $4.03999996$ .

mass of $1$ mole of $C H_{4} O = 16.05000019 + 16 g$

Add $16.05000019$ and $16$ .

mass of $1$ mole of $C H_{4} O = 32.05000019 g$

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 $C = \frac{12.01}{32.05000019} \cdot 100$

Divide $12.01$ by $32.05000019$ .

$0.37472698 \cdot 100$

Multiply $0.37472698$ by $100$ .

$37.47269868$

Set the number as a percent.

Mass percentage of $C = 37.47269868 %$

Step 5

Find the mass percentage of $H$ .

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

Mass percentage of $H = \frac{4.04}{32.05000019} \cdot 100$

Divide $4.04$ by $32.05000019$ .

$0.12605304 \cdot 100$

Multiply $0.12605304$ by $100$ .

$12.60530413$

Set the number as a percent.

Mass percentage of $H = 12.60530413 %$

Step 6

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 $O = \frac{16}{32.05000019} \cdot 100$

Divide $16$ by $32.05000019$ .

$0.49921996 \cdot 100$

Multiply $0.49921996$ by $100$ .

$49.92199658$

Set the number as a percent.

Mass percentage of $O = 49.92199658 %$

Step 7

Find the mass percentage of each element in the molecule.

Mass percentage of $C = 37.47269868 %$

Mass percentage of $H = 12.60530413 %$

Mass percentage of $O = 49.92199658 %$
