Convert the mass of NH_4NO_3 to moles using its molar mass.
Use the balanced chemical equation to determine the mole ratio between NH_4NO_3 and the total moles of gas produced.
Calculate the total moles of gas produced using the mole ratio from the balanced equation.
Apply the ideal gas law, PV = nRT, to find the volume of gas produced, where P is pressure, V is volume, n is moles of gas, R is the ideal gas constant, and T is temperature in Kelvin.
Convert the temperature from Celsius to Kelvin by adding 273.15 to the Celsius temperature.

Stoichiometry

Stoichiometry is the calculation of reactants and products in chemical reactions based on the balanced chemical equation. It allows us to determine the relationships between the quantities of substances involved in a reaction. In this case, stoichiometry will help us find out how many moles of gas are produced from the decomposition of ammonium nitrate.

Stoichiometry Concept

Ideal Gas Law

The Ideal Gas Law relates the pressure, volume, temperature, and number of moles of a gas through the equation PV = nRT. This law is essential for calculating the volume of gas produced in a reaction under specific conditions of temperature and pressure. In this problem, we will use the Ideal Gas Law to convert the moles of gas produced into liters at the given temperature and pressure.

Ideal Gas Law Formula

Gas Volume at STP

At standard temperature and pressure (STP), one mole of an ideal gas occupies 22.4 liters. However, in this question, we need to adjust for the given temperature of 450 °C and pressure of 1.00 atm. Understanding how to apply the Ideal Gas Law in conjunction with the concept of gas volume at STP is crucial for accurately determining the volume of gas produced from the decomposition of ammonium nitrate.
