Answer 1

Explanation:

Boyle's law, also referred to as the Boyle–Mariotte law, or Mariotte's law, is an experimental gas law that describes how the pressure of a gas tends to increase as the volume of the container decreases.

Answer 2

1. Boyles law states that at constant pressure mass of gas is inversely proportional to it's temprature
2. standard temperature equal to 0 degree C and standard pressure is 1 atom
3. Mass of nitrogen=14

NH4NO3=14x1 + 1x4 + 16x3

=14+4+48

=66

percentage of nitrogen in ammonium nitrate

$\frac{14}{66} \times 100$

=21.2121
