- 1. One of the first families of rockets used by the American space program was the Redstonefamily of rockets. The first Redstone rockets (in the 1950s) used B10H14 (often called decaborane)as a rocket fuel that reacts violently with liquid di-oxygen to make diboron trioxide and steam.When used as a rocket fuel, scientists carefully calculated the amount necessary so that bothcomponents ran out at the same time. (Excess fuel would be excess weight for the rocket tocarry.) If the total mass of both reactants put together is 12.0 104 kg, what was the volume ofliquid di-oxygen carried by the rockets?
