    Using a rocket to visit the space station requires 119 trillion BTU of energy. The best fuel for the mission will have the highest ratio of energy to volume. Based on the full data presented in the table, select the optimal fuel and calculate total gallons of fuel required. Table: Energy Output BTU/lb Density g/ml Kerosene 18,500 0.820 Gasoline 20,900 0.737 Ethanol 11,500 0.789 Hydrogen(l) 61,100 0.0710 Which is the optimal fuel? How many gallons of fuel are required? Conversion units:convert energy output to BTU/gal 1000ml=1 l 454 g=1lb 3.785 L=1 gal 1 trillion=1 X 10^12

      The optimal fuel will be that which gives you maximum energy for a given volume..in these options hydrogen will be the best suited fuel as for it gives maximum energy for 1 ml ..
