Solution

The correct option is B 35%, 60%
Molar mass of ammonium nitrate( $N H_{4} N O_{3}$ )= 80 gm
% of oxygen $= 48 \times \frac{100}{80} = 60$
% of nitrogen $= 28 \times \frac{100}{80} = 35$

(i) LPG stands for liquefied petroleum gas. Varieties of LPG are marketed including a mixture of propane (60%) and butane (40%). If 10 litre of this mixture is burnt, find the total volume of carbon dioxide gas added to the atmosphere. Combustion reactions can be represented as:
