This is expressed as the weight of a mineral compared with the weight of an equal volume of water?
This is the specific gravity of the mineral. It's a comparison of how much mass a given volume of it has compared to the mass of an equal volume of water.
How do you calculate the denstiy of pyrite?
Compare its weight to the weight of an equal volume of water. The weight of the specimen divided by the weight of the water equals the density of the specimen.
How to calculate mass of water from density?
You have to use the density equation... D = M / V D= density M= mass V= volume You have to find the volume of your water. Since you know your density the only thing left to find out is the mass. Just solve for it by multiplying the volume times the density.
How do you figure out rock Density?
Density is actually a comparison of two things. It's a RATIO. It is a comparison of the mass of something and the volume of that thing. Once we know an object's mass and its volume, we set up a ratio, and that will be the density. Weigh the rock. Put it on a scale. Let's say it weighed 100 grams. Then find its volume. Partially fill a graduated measuring container with water to s fixed level, drop in the rock, and then see how much the water level rose. That will be the volume. Let's say 10 cubic centimeters. Construct your ratio. 100 grams : 10 cubic centimeters We need to refine this a bit so we can make comparisons of the density of one thing to that of another. Let's reduce both measurements by a factor of ten. Dividing both the measurements by ten yields this: 10 grams : 1 cubic centimeter That's ten grams per cubic centimeter for the density of your rock. Grams per cubic centimeter is a common SI expression of the density of a material. If one looked up the density of, say, metals, for example, that's the way they would most likely be found.
Difference between density and specific gravity?
Density is measured by mass per volume and the expressed formula is P=M/V where P represents Density, M represents Mass and V represents Volume. Specific density is a measurement of density relative to another substance and the expressed formula is Substance=P substance/ P reference. An example of specific density is measuring salt in ocean water and comparing it to salt in fresh water.
a comparison of density to the density of an equal volume of water?
Density
This is expressed as the weight of a mineral compared with the weight of an equal volume of water?
This is the specific gravity of the mineral. It's a comparison of how much mass a given volume of it has compared to the mass of an equal volume of water.
What is a force helps a ship float?
Buoyant force = Density of the water * g * Volume of displaced water For the ship to float, the buoyant force must be equal to the weight of the ship. Density of the water * g * Volume of displaced water = m * g Density of the water * Volume of displaced water = m When you multiply the density of water by the volume of displaced water, you get the mass of the ship.
How do you prove that the mass of a substance of a density is equal to the volume of water?
Submerse the object in a completely full bucket. measure the volume of the displaced water due to the object. Multiply the volume of the displaced water by the density of the object to give mass.
How does the amount of buoyant force exerted by water vary with the volume of submerged solid?
The amount of buoyant force is equal to the weight of the displaced water. The VOLUME of the displaced water is equal to the part of the solid that is submerged - thus, the buoyant force is equal to this volume, times the density of the water.
Would an object of g in volume and cm cubed be able to float in water?
An object will float in water if it has less density than the water. You can calculate the density of the object by dividing its mass by its volume. For comparison, the density of water is: * 1 gram / cubic centimeter * 1 kilogram / liter * 1000 kilograms / cubic meter
What is the difference between specific gravity and density?
Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water.
When the specific gravity equal to density?
Specific gravity and density will have the same value when the two substances under investigation have identical densities. Density is an expression of the amount of mass per unit of volume that a substance exhibits. Specific gravity is a comparison of the density of a substance to the density of water.
How do you find mass if you you have volume and density?
the units of density are mass/volume so anything that gives you those variables. A scale and graduated cylinder be used if you fill the cylinder with water and the monitor the displacement of the water. 1ml of water is equal to 1 cubic cm (thats volume)
How do you find buoyant force and volume immersed?
Buoyant force is equal to the weight of the volume of water displaced. Buoyant force = [density of water] x [volume of water displaced] x [gravity]
Does the volume of water change the density of water?
Density = mass / volume. So if the volume changes, the density will obviously also change.
Find the density of water?
Measure out a specific volume of water, such as 100mL. Determine the mass of that volume of water. Density = mass/volume, so divide the mass by the volume, and you will have the density.
