Find the Mass Percentages MnO_4

$M n O_{4}$

Step 1

To find the mass of $1$ mole of $M n O_{4}$ 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 $M n O_{4}$ $=$ $(mass of Mn)$ + $4 (mass of O)$

Step 2

Fill in the atomic masses from the periodic table.

mass of $1$ mole of $M n O_{4}$ $=$ $(54.93999862)$ + $4 (16)$

Step 3

Simplify the result.

Multiply $4$ by $16$ .

mass of $1$ mole of $M n O_{4} = 54.93999862 + 64 g$

Add $54.93999862$ and $64$ .

mass of $1$ mole of $M n O_{4} = 118.93999862 g$

Step 4

Find the mass percentage of $M n$ .

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

Mass percentage of $M n = \frac{54.94}{118.93999862} \cdot 100$

Divide $54.94$ by $118.93999862$ .

$0.46191357 \cdot 100$

Multiply $0.46191357$ by $100$ .

$46.19135752$

Set the number as a percent.

Mass percentage of $M n = 46.19135752 %$

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 $O = \frac{64}{118.93999862} \cdot 100$

Divide $64$ by $118.93999862$ .

$0.53808643 \cdot 100$

Multiply $0.53808643$ by $100$ .

$53.80864363$

Set the number as a percent.

Mass percentage of $O = 53.80864363 %$

Step 6

Find the mass percentage of each element in the molecule.

Mass percentage of $M n = 46.19135752 %$

Mass percentage of $O = 53.80864363 %$
