Ответ:
Moles of N2 = 14 g/(28 g/mole) = 0.5 mole
Moles of H2 = 28 g/(2 g/mole) = 14 mole
Because the reaction ratio between N2 and H2 is 1:2, for a complete reaction of 0.5 moles N2, 1 mole H2 is needed. Clearly there are excess amount H2 present. So N2 is the controlling factor.
The ratio between N2 and N2H4 is 1:1, so the maximum moles of N2H4 generated from the reaction is also 0.5 mole. The maximum mass of N2H4 is 0.5 mole * 32 g/mole = 16 g.
