Find the Mass Percentages BaNO_3

$B a N O_{3}$

Step 1

To find the mass of $1$ mole of $B a N O_{3}$ 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 $B a N O_{3}$ $=$ $(mass of Ba)$ + $(mass of N)$ + $3 (mass of O)$

Step 2

Fill in the atomic masses from the periodic table.

mass of $1$ mole of $B a N O_{3}$ $=$ $(137.33000183)$ + $(14.01000022)$ + $3 (16)$

Step 3

Simplify the result.

Remove parentheses.

mass of $1$ mole of $B a N O_{3} = 137.33000183 + 14.01000022 + 3 (16) g$

Multiply $3$ by $16$ .

mass of $1$ mole of $B a N O_{3} = 137.33000183 + 14.01000022 + 48 g$

Add $137.33000183$ and $14.01000022$ .

mass of $1$ mole of $B a N O_{3} = 151.34000205 + 48 g$

Add $151.34000205$ and $48$ .

mass of $1$ mole of $B a N O_{3} = 199.34000205 g$

Step 4

Find the mass percentage of $B a$ .

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

Mass percentage of $B a = \frac{137.33}{199.34000205} \cdot 100$

Divide $137.33$ by $199.34000205$ .

$0.68892344 \cdot 100$

Multiply $0.68892344$ by $100$ .

$68.89234402$

Set the number as a percent.

Mass percentage of $B a = 68.89234402 %$

Step 5

Find the mass percentage of $N$ .

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

Mass percentage of $N = \frac{14.01}{199.34000205} \cdot 100$

Divide $14.01$ by $199.34000205$ .

$0.07028192 \cdot 100$

Multiply $0.07028192$ by $100$ .

$7.02819296$

Set the number as a percent.

Mass percentage of $N = 7.02819296 %$

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 $O = \frac{48}{199.34000205} \cdot 100$

Divide $48$ by $199.34000205$ .

$0.24079461 \cdot 100$

Multiply $0.24079461$ by $100$ .

$24.07946197$

Set the number as a percent.

Mass percentage of $O = 24.07946197 %$

Step 7

Find the mass percentage of each element in the molecule.

Mass percentage of $B a = 68.89234402 %$

Mass percentage of $N = 7.02819296 %$

Mass percentage of $O = 24.07946197 %$
