Answer :

The ammonium nitrite that we are going to use is 6.4 g.

To use stoichiometry

The law of conservation of mass, is the basis of what we ant to do in the solving of the task that is at hand., is the foundation of stoichiometry. As a result, the total mass of the reactants and the total mass of the products must match.

The reaction's equation is;

[NH4]NO2 N2 + 2H2O

There is pressure would be 95.3 kPa, or 0.94 atm

PV = nRT

n = PV/RT

n = 0.94 * 2.58/0.082 * 294

n=0.1 moles.

Mass of the ammonium nitrite is; if the reaction is 1:1.

64 g/mol * 0.1 moles
