maybe when you are want to now or NERVER !
Is this the density of a liquid or an object? If this is the density of a liquid and you want to make an object float, than the density of the object should be less than 2.7. If this is the density of an object you are trying to make float, than the density of the liquid should be greater than 2.7.
An object will float in water if its density is lower than water which means that for an object to float, its density needs to be less than ~1 gram/centimeter^3,
You can't. Volume is the space occupied by a substance or object. To find the volume from the mass, the density would have to be known. Density = Mass / Volume If you want to find any of the three, you need the other two.
It depends on what you want to float it on. For instance if you want to float a ball in oil the ball's density must be less than the oil's density.
You use water displacement and plug the numbers into the density equation. Below is a step by step guide on how to use it. 1. Get a graduated cylinder, or anything that you can measure water in. 2. Fill the graduated cylinder with water. 3. Record the volume 4. Place the object you want to find the density of in the water. 5. Subtract the value you got in #3 from #4. This number represents the volume of the object you want to find the density of. 6. Take the object you want to find the density of, and weigh it. 7. Then take the 2 numbers you got and plug them into the formula d=m/v D=density, m=mass (weight in grams), v=volume NOTE: The ONLY liquid you can use for water displacement is WATER!
If you want to determine the density of an object, you would measure the mass and volume, then divide mass/volume to determine density. This can help determine the composition of the object. For example, if you find a rock that looks like a gold nugget. The density of gold is a known value, so one of the tests in determining if you are holding real gold would be to determine the density of your rock. This is one example. Another (maybe more 'real world' for you). Shipping and cargo companies measure the volume of packages as they go by on the conveyor belt, so that they can figure how many will fit in a particular truck.
Assuming you want density: 18 g/3 cm3 = 6 gcm-3
ANSWER:No. The mass will be halved but the density will remain the same. ___________________________________________________________The density will remain the same since the formula for density of an object is mass/volume. When you split and object, the mass is divided by 2, and the volume is divided by 2 (or whatever fraction you want to cut your item). If you would, compare mass/volume=mass divided by 2/volume divided by 2.
If a object has buoyancy it floats. A object also needs to have a density less dense than the object you want it to float on. Example: if you want a inner tube to float and jewelry to sink you make them out of different materials.
Not at all. You can paint styrofoam or granite any color you want. Also, gold and blond hair have similar color but substantially different density.
What do you want to measure - mass, weight, volume, density. There's no answer for "measure" without indicating what is to be measured.
don't have a clue want to find it out not tell the answer) cause i don't have the answer
