Ammonium nitrate has been used as high explosive because its unstable & decomposes into several gaseous substances. The rapid expansion of the gaseous substances produces the explosive force.

Question

NH4NO3-->N2+O2_H2O

Calculate the mass of each product gas if 1.25g of ammonium nitrate reacts.

Answer 1

Balance the equation.
Convert 1.25 g NH4NO3 to moles.
Convert moles NH4NO3 to moles N2, moles O2, and moles H2O. (Three conversions each done separately).
Convert moles of each to grams of each.
