Hydrazine, N2H4 is used in rocket fuels. The thermochemical equation for the combustion of hydrazine is: N2H4 + O2 → N2 + 2H2O + 622.4 kJ
a) How many grams of H2O will be produced if 1.5 of N2H4 is used?
Mole ratio of H2O to N2H4 = 2:1
Therefore, 1.5 moles of N2H4 = 3 moles of H2O
Molar Mass of H2O = 18.01528
= 18.01528 ×3
= 54.04584 g
