What is the Density of Water with volume of 18 Cm?

Assuming standard (pure, clean) water, and standard temperature and pressure,the density of any amount of water is always 1.In order to find the density of a substance, you don't need to know mass or volume.You only need to know what the substance is. That's the whole point of 'density'.


How do you convert 464.5 liters to kilograms?

You need to know the density but if that is 1 (based on density of water), then 464.5 litres is 464.5kg


What is the density of quart of water and the density of a teaspoon of water are the what?

I do not know


Why do you need to know the density of things?

To have knowledge about their property in the real physical world. You can also calculate how much mass an object has if you know how big it is. For example: * Low density objects floats on water. * High density objects sink in water.


What is the density of water with 50 grams of salt in it?

If water froze (ice), then it would be less dense than the water itself.


What two properties must you know to determin density?

Density is a measure of mass to volume. The density of water at 4C is 1 g/ml. So to determine density of a substance you need to know the mass and the volume. Any density higher than 1 will sink in water and any density lower than 1 will float.


What do you know about the density of water?

I do know about the density of water. The density of water is 1.0 grams/ millimeter. To find the density of an object, divide its mass by volume. If you have any further questions, ask me.


How do you calculate the mass of water from its density?

You know that the density of pure water is 1g/cm3. If you also know the volume of the water, you can multiply the two and get the mass.


How do you know whether a substance has a greater density than water?

If it sinks in water then it has a higher density than water. If it floats on water surface then its density is less than water.


How many liter are in one tonnage?

For water: 1 tonne = 1 000 L For other materials you need to know the density; mass = volume x density.


What two thing you need to know to calculate density?

Density is mass per volume, so you need to know mass and volume.


How do you know if a compound has a density less than 1 gmL?

If it floats in water, it has a density less than water. Density of water is 1.0 g/mL
