Assume that coal can be represented by the chemical formula c135h96o9ns. if 4.0 tons of coal is burned, what mass of nitrogen is found in the no produced by this process?

26653.9 grams of nitrogen is found in the nitrogen dioxide produced by this process.

Explanation:

Mass of the coal = 4.0 tons  

1 ton = 907185 g

Molar mass of coal = 1,906 g/mol

Moles of coals =

According to reaction,  1 mole of coal gives 1 mole of nitrogen dioxide gas.

Then, 1,903.85 mole of coal on combustion will give:

of nitrogen dioxide gas

1 mole of nitrogen dioxide gas has 1 mole of nitrogen atom.Then 1,903.85 moles of nitrogen dioxide will have ;

of nitrogen

Mass of 1,903.85 moles of nitrogen dioxide gas :

1,903.85 mol × 14 g/mol = 26653.9 g

26653.9 grams of nitrogen is found in the nitrogen dioxide produced by this process.
