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 ..
