What is the density of a mineral sample?
The density of a mineral sample is a measure of its mass per unit volume. It can be calculated by dividing the mass of the sample by its volume. The density of a mineral sample is a characteristic property that can help in identifying the mineral.
What is the volume of graphite?
The volume of graphite is dependent on its mass and density. You can calculate it only if you know the sample's mass and density. The same goes for any other substance or object.
What is the identity of a sample that has a mass of 2.44 g and a volume of 0.34 cm3?
The identity of the sample can be determined by calculating its density, which is mass divided by volume. In this case, the density would be approximately 7.18 g/cm³. By comparing this density to known values for different substances, you can identify the sample based on its density.
Why does the density of a substance not change with the sample size?
The density of a substance does not change with the sample size because density is an intrinsic property of the material, determined by its mass and volume. As you increase the sample size, both the mass and volume of the substance increase proportionally, resulting in no change in density. This relationship is described by the formula density = mass/volume, which remains constant regardless of the amount of the substance being measured.
How do you calculate the density in grams per cubic centimeters?
-- Take an object or a sample of a substance-- Measure its mass, and express the result in grams-- Measure its volume, and express the result in cubic centimeters-- Divide the mass by the volume. The result of the division is the density of the object or substance,expressed in "grams per cubic centimeter".
What is formula of density?
The density of an object or a sample of a substance is (the object's mass) divided by (its volume).
What is the formula for the density of a irregular shaped object?
Density = (mass) divided by (volume)regardless of the substance, or the shape of the sample.
What is a sample of iron has the same dimensions of 2 cm x 3 cm. if the mass of this rectangular-shaped object is 94 g what is the density of iron?
The volume of the iron sample is length x width x height = 2 cm x 3 cm x unknown height. We know that the mass is 94 g. The density of iron is mass/volume, so you can calculate the height of the sample first and then plug in the values to find the density.
What is the mass of a sample divided by its volume?
Its density. Density is mass per unit volume.
How are density and buoyancy are alike?
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.
Why does the density of an object stay the same for different amounts of the object?
Density is an intrinsic property of a material that remains constant regardless of the sample size. This is because density is defined as the mass of a substance per unit volume, so as long as the composition of the material and its volume remain constant, the density will not change.
How do you find the density of an irregular shaped object that also reacts with water?
We will assume there is no difficulty in weighing the object, so the problem becomes how to measure the volume of the object accurately enough to calculate the density within a reasonable degree of certainty. There are several possible ways.Immerse the object in a non-reactive liquid (oil, perhaps) and measure the amount of liquid displaced.Apply a thin coat of insulating material (paint, or wax) all over the object, and then immerse the coated object in water and measure the amount of water displaced.Cut the object into a group of regular geometric shapes (boxes, spheres, prisms, cones, pyramids, etc.), and measure the dimensions of each geometric shape, and calculate the aggregate volume (destructive, and less accurate)Drill a cylindrical core sample of the object, weigh the sample, and precisely measure the dimensions of the cylindrical sample to calculate volume (destructive, and assumes the density of the object is uniform)Make a clay, wax, or other mold of the object, and measure the volume of the mold.Place the object in an three dimensional laser scanner and compute the volume using the software in the scanner computer.
Is it true that the density of a sample depends on it location on earth?
No, the density of a sample does not depend on its location on Earth. Density is a physical property of a substance that remains constant regardless of its location. However, the gravitational force acting on an object can affect its weight, which may give the appearance of a change in density when in fact it remains the same.
How do you test the density of wood?
One common method to test the density of wood is to measure the mass and dimensions of the wood sample, then calculate its volume. By dividing the mass of the wood sample by its volume, you can determine the density of the wood in grams per cubic centimeter. Another method is to use a densitometer, a device specifically designed to measure the density of materials like wood.
What is the eqyaion for density?
Density of a substance = (mass of a sample of it)/(volume of the same sample)
How are weight of mass relate to density?
Density has dimensions - for instance grammes per cubic centimetre. Relative density is dimensionless - it is a density compared to another density - it is a dimensionless ratio. Normally the ratio is based on water, which has a density of 1g/cm3, so density and relative density are usually the same number - one with units, one without.
How do you calculate the weight of a solid object?
Find the volume of the sample (Length times width times height) and multipy by the density coefficient.
