Question

Calculate the mass percent of different elements present in sodium nitrate (NaNO3)​

Answer 1

Explanation:

Percent composition by element

Element Symbol Mass Percent

Sodium Na 27.048%

Nitrogen N 16.480%

Oxygen O 56.472%

Answer 2

Given:

Sodium nitrate ($\[NaN{O_3}\]$)​

To Find: Mass percent of different elements present in sodium nitrate

Solution:

The molecular mass of sodium nitrate can be given as:

Molecular mass $\[ = 23 + 14 + 3 \times 16\]$

Molecular mass $\[ = 85\]$

Therefore, the mass of different elements can be given as:

Sodium:

$\[\frac{{23}}{{85}} \times 100 = 27.05\% \]$

Nitrogen:

$\[\frac{{14}}{{85}} \times 100 = 16.47\% \]$

Oxygen:

$\[\frac{{48}}{{85}} \times 100 = 56.47\% \]$

Hence, the mass percent of different elements (Na, N and O) are $\[27.05\% ,\,16.47\% \,and\,56.47\% \]$ respectively.
