Answer:
A)0.450 mol N2
B)294 g NH4 NO3
Explanation:Step by step! make sure when you see underneath the multipication eqaution that we are deviding!The arrows is what we are dividing
A)36.0gN H4N O3×1 molN H4NO3×2mol N2
↑ 1 ↑ 80.05gNH4NO3 ↑2mol N H4N O3
B)7.35molH2O×2mol N H4 N O3×80.05gN H4 N O3
↑ 1 ↑ 4molH2O ↑ 1mol N H4N O3
5) 2 and for the how many moles it is 10.9
Hope this helps!
