the specific gravity is how the density of the object compares to the density of water. Water's density is 1gram per milliliter. We just need to figure out the density of the object.
The object is .8 kg and it displaces 500mL of water, so the density is the mass divided by the volume. Since the density of water is given in grams, we have to convert the objects mass from kg to g and then we can get the density.
.8kg * 1000g/kg = 800 grams
so,
800g/500ml = 1.6grams/mL this is the density.
So divide the density of your object by the density of water, which is 1g/mL, you get 1.6 as the specific gravity. This means the object is 1.6 times more dense than water.

Why is the reason an object floats in water?
If the volume of liquid the object displaces weighs more than the object, the object will float. The principle is buoyancy or specific gravity.
Why the weight of certain objects in water is zero?
If the object has the same density as water (specific gravity=1) then the weight of the object will be equal to the weight of water it displaces, so it will have neutral buoyancy and apparently weigh nothing. If the object has a lower density than water (specific gravity<water) then it will have positive buoyancy - like a piece of polystyrene foam - and will float on the top of water. In effect the excess weigh of the water it displaces is pushing it up. If the object has a higher density than water (S.G.>1) then it will sink, outweighing the volume of water it displaces. Google "Archimedes Principle". Note that the density of water can vary. Pure water has a density, or specific gravity, of 1.00, but sea water is denser due to the dissolved salt, which is why you can float more easily in the ocean. (The Dead Sea is an extreme example.) Alcoholic drinks are less dense than water, because of the ethanol they contain, and measuring their specific gravity gives a guide to their strength.

the specific gravity is how the density of the object compares to the density of water. Water's density is 1gram per milliliter. We just need to figure out the density of the object. The object is .8 kg and it displaces 500mL of water, so the density is the mass divided by the volume. Since the density of water is given in grams, we have to convert the objects mass from kg to g and then we can get the density. .8kg * 1000g/kg = 800 grams so, 800g/500ml = 1.6grams/mL this is the density. So divide the density of your object by the density of water, which is 1g/mL, you get 1.6 as the specific gravity. This means the object is 1.6 times more dense than water.
Specific is the ratio of an object's density to that of water?
Specific Gravity.
What can you say about the specific gravity of an object that floats in water and the specific gravity of an object that completely submerges in water?
S.G. of water = 1.0 Floating, S.G. < 1.0, Submerging, S.G. > 1.0.
The density of gold is 19.3 A piece of gold displaces 2 ml of water The specific gravity of gold is?
19.3. Specific gravity is another way of saying density.
What is equal to the volume of water an object displaces?
volume of water an object displaces is equal to the volume of the part of the object inside it
What has a specific ratio of an object's density to that of water?
It is called the specific gravity.
What is the ratio of an object's density to the density of water is called the object's?
specific gravity
What is the term for the ratio of an object's density to that of water?
Specific Gravity.
What determines wether an object will float in water?
An object will float in water if the object's density is less than the density of water. Relative density is the ratio of one object density with respect to the density of another object. Relative density of any object with respect to water is also known as specific gravity. Objects with a specific gravity less than one will float those with a specific gravity greater than one will not.
How can you identify rhodium with no markings?
Take a specific gravity test. First weight the object in grams Second Find how much water it displaces using a fixed amount of water in a measurable crucible with ml measurements. Place the object in the water. Remember 1 ml = cm^3 (cubic centimeter) volume Weight in grams divided by volume equals density (Specific Gravity) Take the result and compare with the Specific Gravity of Rhodium 12.45 grams/cm^3 (this is for 100% pure) You are welcome
