Answer:
5.355 g
Explanation:
first you have 30.6 g from ammonium nitrate ( NH4NO3 )
molecular weight for NH4NO3 is 80 g/mole
and molecular weight for nitrogen gas N2 is 14 g/ mole
make this
NH4NO3 --------------> N2
80 g/mol --------------> 14 g/mol
30.6 g ---------------> x
So X = 14 x 30.6 ÷ 80 = 5.355 g of N2
Good Luck
