Well that is true. But remember the time.
I can't find that rocket. But here are some stats for a V-2. Note the time of burn and the amount of alcohol it burns in that time. (In bold stuff)
Link
Power: Liquid-fuelled rocket motor
Ethyl Alcohol (75%): 8179 lb, 3710 kg
Liquid-oxygen: 10802 lb, 4900 kg
Warhead: 1627 lb of explosives, 738 kg
(not high explosives, because of frictional warmth exceeding 1200 degrees F during flight)
Launch weight: 12.8 tons, 13000 kg
Hydrogen Peroxide 285 lbs, 129 kg
Sodium Permanganate 35 lbs, 15.8 kg
Nitrogen 30 lbs (Nitrogen has multiple services, the difficult valve system is operated by it and the pressure in the alcohol tank)
Thrust at liftoff: 55100 lb, 25,000 kg
