------------------------------------------------ Calculate the total volume of gas (at 128 [tex]^\circ[/tex]C and 753 mmHg) produced by the complete decomposition of 1.50 kg of ammonium nitrate.

To calculate the total volume of gas produced from the decomposition of 1.50 kg of ammonium nitrate, we first need the balanced chemical equation, then convert the mass to moles, and use the ideal gas law to find the volume at the given conditions of 128 ℃ and 753 mmHg.

Explanation:

The student's question involves the calculation of the total volume of gas produced from the decomposition of ammonium nitrate at given conditions (128 ℃ and 753 mmHg). To solve this, we must first write the balanced chemical equation for the decomposition of ammonium nitrate (NH4NO3):

NH4NO3 → N2O(g) + 2H2O(g).

Next, we convert the mass of NH4NO3 (1.50 kg) to moles using its molar mass. Then, using the ideal gas law (PV=nRT) and the given conditions, we can calculate the volume of the produced gas. Finally, we need to adjust the values to Standard Temperature and Pressure if required by the student's curriculum.
