Ice has a density of 916,8 kilograms per cubic meter or 0.9128 grams per cubic centimeter. 20 cubic meters of ice weigh then 20 times 916,8 = 18336 kilograms = 18.336 tonnes.

Do scientists use the measure of density to tell if something will float?
yes. for example; Ice is just frozen water, right? So why does ice float in water? When we find the mass of an ice cube and divide that by its volume, we come up with about .92. Ninety-two hundredths is less than one, so the density of ice is less then that of water. Ice floats because the ratio of its mass to volume is less than one.
Why does water sink to the bottom of a glass but ice floats?
good question..first i want to say why a body floats in any liquid?the answer is it only due to the density.If the density if the body is less than that of the liquid then the body floats in that particular liquid.there is nothing to do with the weight.Yes we can say that the density is directly propertional to the mass but yes that is also inversely propertional to the volume.the relationship is given as ,density=(mass)/(volume)now come to the ice and water.as the density of the ice is less than that of the water so the ice floats in the water.now a question arises how i know that the density of ice is less that that of the water?we know if the same amount of the water coverts to the solid form(ice) then the volume increases but the mass is same so acording to the relation the density decreases.I think u got the answer.Because of the lower density in ice, pressure is altered (P=pgh) where height is the depth of water. Because the pressure is greater at the bottom of the ice than the top (greater h), an unbalanced, upwards force, a.k.a buoyancy, is exerted. Therefore ice floats on water
Which has greater density ice or water how can you say that?
Water has a greater density than ice.
What can density mass and volume help to tell you about a substance?
This is the density.
The property of ice that allows it to float in water is the ice's low?
density
If a Sample of ice has a volume of 1.0 cm and a mass of 0.9 g what is the density?
ice=0.9167
How do you calculate mass of ice?
volume*density
How do you find the density of ice?
This density is measured by several methods; the simplest is with the formula density=mass/volume.
What are the volumes of 1.000g of ice and of 1.000g of water at 0 degrees celsius?
Ice VolumeThe density of ice is 0.9167 g/mL; the given mass is 1.000gVolume = mass/density= 1.000 g/0.9167 g/mL= 0.9167 mLWater VolumeThe density of water is 0.9998 g/mL; the given mass is 1.000gVolume = mass/density= 1.000 g/0.9998 g/mL= 0.9998 mLThe volume of ice is 0.9167ml and the volume of water is 0.9998 mL
Density is defined as the mass per unit volume The density of ice is 0.92 gcm3 An ice cube 1.0 inch on a side has a mass of?
density = 0.92 g/cm^3 = 12.718 g/in^3 (1 in = 2.4 cm) vol = 1 in^3 mass = density x vol = 12.718 g
What is the mass of the same volume of ice at 0 c?
Ice density is 0,9167 g/cm3 at oC.
What happens to the mass when water freezes?
No, as long as it is the same peice of ice. The volume and the density change but not the mass
How dense can ice get?
To calculate the density of any object all you need to do is measure the mass and volume. Density = mass/volumeThe density of ice is less than water(which is why only the top of lakes freeze in the winter). For those that want to find the density while it is floating in water look below: Imagine a cube of ice floating in water. In order for it to float the force of gravity on the ice must equal the force of buoyancy on the ice. The force of buoyancy as described by Archimedes is equal to the mass of water displaced by the ice. Lets say the ice is x cm below the level of the water. then: force buoyancy = (density of water)*volume*gforce buoyancy = (density of water)*(area of ice cube)*x*g where g is the acceleration due to gravity equating this to the force of gravity gives: (density of water)*x = (density ice)*(total height of cube) hope that helps.
Is ice denser than vacuum?
Density = (mass) divided by (volume)Since the mass of any region of vacuum is zero, the density of vacuum is zero.So the density of any material is greater than the density of vacuum.
How would you describe a cup of water and a cup of ice using the properties of mass weight volume and density?
Mass of ice less than that of water.Weight (other than in space) of ice less than that of water. Volume of both the same. Density of ice less than that of water.
What is the density of A 6 cm3 block of ice with a mass of 4 grams?
The density of the 6 cm3 block of ice is approximately 0.67 grams/cm3. This can be calculated by dividing the mass (4 grams) by the volume (6 cm3).
What is the density of an ice cube with a mass of 18.75 grams and a volume of 3.1 cubic centimeters?
Density = mass/volume = 18.75 g/3.1 cc = 6.0 g/cc (2 sig figs)
