Its all to do with the concepts of volume and weight.
Using a system called Specific Gravity, you can work out how much a set amount of liquid will weigh.
For example. Fresh water has a specific gravity of 1. Its what we base all other liquid weights upon. So 1000 litres of fresh water will weigh exactly 1 metric tonne (1000kg)
Oils generally have a lower specific gravity, all conventional oils certainly do, than water. So they are 0.85, 0.95 etc.
Unleaded Petrol has a specific gravity of approximately 0.72, so 1000 litres of it will weigh 720kg. 1 litre would weigh 72 grams.
The calculation is volume * specific gravity = weight.
Hope this helps.

Oil or gas floats on water, petrol would be the lighter.
What else can I help you with?
Which weighs more a liter of water at 20 C or 1 dm3 piece of ice at -4 C?
A liter of water at 20 C weights more.
What weights a little more than a liter?
A liter is not a unit of weight. A liter is a unit of volume (equal to one cubic decimeter).
How much petrol deos 1.4 liter engine car need?
ask answers.com It depends on how far you want to go. The more petrol, the farther you go.
What weighs more a liter of water or a liter of oil?
A liter of water weighs more than a liter of oil because the density of water is higher than that of oil. The weight of a liter of water is around 1 kilogram, whereas the weight of a liter of oil can vary depending on the type of oil.
How does petrol evaporate faster than water?
It is more volatile than water.
What weighs more 1 liter water or 1 kg soil?
Utilizing the fact that the density of water is somewhat less than 1 kg/L at a temperature of 20 degrees Celsius, we are able to deduce that the 1 kg soil weights somewhat more.
Is coke more expensive than petrol?
The price of Coke and petrol varies significantly based on location, market conditions, and packaging. Generally, petrol is more expensive per liter than Coke, which is often sold at a lower price per liter, especially in bulk or larger quantities. However, prices can fluctuate, so it's essential to check local prices for an accurate comparison.
How do you make water weights heavier?
You can make water weights heavier by adding more water to the container or by using a denser liquid, such as sand or gravel, in combination with water. Increasing the volume or density of the liquid will increase the weight of the water weights.
What will have more molecules 1 liter of water or 1 liter of ice?
1 liter of water will have more molecules than 1 liter of ice. This is because in ice, the water molecules are arranged in a more spaced out, structured manner compared to the closely packed water molecules in liquid water.
Petrol can be separete with the water?
Yes, petrol and water can be separated using a process called gravity separation. Petrol, being less dense than water, will float on top of the water, allowing them to be easily separated. Alternatively, a specialized separation technique like distillation can also be used to separate petrol and water more effectively.
How far liter of petrol?
The distance that can be traveled on one liter of petrol varies significantly based on factors such as the vehicle's fuel efficiency, driving conditions, and driving habits. On average, many cars achieve around 12 to 15 kilometers per liter. However, more fuel-efficient vehicles can travel over 20 kilometers per liter, while larger or less efficient vehicles may cover less than 10 kilometers per liter. Always check the specific fuel economy rating for your vehicle to get a more accurate estimate.
What is heavier 1 liter of air or 1 liter of water?
Water because a liter is a measurement of space and not mass. Water occupying 1 liter of space is lots heavier than air occupying 1 liter of space. <><><><><> It depends on density. It is possible, given enough pressure, to have one liter of air weigh more than one liter of water.
