Answer:

0.02 tons of NO produced when 4 tons of coal is burned

Explanation:

From the given,

Chemical formula of coal =  C_{134}H_{96}O_{9}NS

Molecular mass of coal = (134\times12)+(9\times1)+(9\times16)+14+32\,=1906.1gm

Let’s calculate the mass of nitrogen in coal

Percentage\,weight\,of\,nitrogen=\frac{Mass\,of\,nitrogen}{Molecular\,mass\,of coal}

Percentage\,weight/,of/,nitrogen=\frac{14}{1906.1}=0.73%

Amount of coal burnt = 4tons

Amount of NO produced by burning 4tons = 4\,tons\,of\,coal\times \frac{0.73tons}{100\,tons\,of\,coal}=0.0292\,tons

This nitrogen is converted into NO by reacting with atmospheric oxygen.

Answer:

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

Explanation:

C_{135}H_{96}O_9NS + \frac{313}{2}O_2\rightarrow 135CO_2 + 48H_2O+ NO_2 + SO_2

Mass of the coal = 4.0 tons  

1 ton = 907185 g

4.0 tons = 4\times 907185g=3,628,740 g

Molar mass of coal = 1,906 g/mol

Moles of coals = \frac{3,628,740 g}{1,906 g/mol}=1,903.85 mol

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:

\frac{1}{1}\times 1,903.85 mol=1,903.85 mol 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 ;

1\times 1,903.85 mol=1,903.85 mol 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.
