Assume that coal can be represented by the chemical formula C135H96O9NS. If 4.0 tons of coal is burned, what mass of nitrogen is
Schach [20]

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.
