Hypergolic propellants are fuels and oxidizers which ignite spontaneously on contact with each other.requiring no ignition source, hypergolics are ideal for spacecraft maneuvering systems as they provide an easy start and restart capability. Also, hypergolics do not pose the storage problems of cryogenic propellants (e.g., liquid oxygen and hydrogen) as they remain liquid at normal temperatures. This technology was used on the Apollo 11 Mission 40+ years ago. As part of the testing for a new thruster design, amounts of unsymmetrical dimethyl hydrazine, or UDMH [(CH3)2N-NH2; MW=60.1 g/mol] were reacted with dinitrogen tetroxide [N2O4; MW=92.1 g/mol]. The balanced equation for this reaction is shown below: (CH3)2NNH2(l) + 2 N2O4(g) → 3 N2(g) + 4 H2O(g) + 2 CO2(g) For one test, 721.2 grams of UDMH was completely consumed. How much dinitrogen tetroxide [in grams] was needed?
