What is the density if a 2750 g sample of a substance occupies a volume of 250 cm3?
Provided that the substance you're referring to is a liquid or a solid (which I'll assume it is, judging by the large mass) you would calculate the density by dividing the mass (475g) by the volume (250cc) giving you a measurement in grams per cubic centimeter. In this case...
475g/250cc=1.9g/cc
The only difference for a gas is that the density can be calculate in grams/liter instead. in which case the equation would be:
475g/.250L = 1860g/L Which is almost twice the density of water @ 5 degrees Celsius.
What else can I help you with?
Does each sample occupies space?
Yes, each sample of a substance occupies space due to its physical dimensions and the volume it occupies in a container. The amount of space a sample occupies is known as its volume.
How does the volume and density of a substance change when it is heated?
When a substance is heated, its volume generally increases due to thermal expansion. On the other hand, the density of the substance usually decreases since the same amount of matter now occupies a greater volume.
How could density be used to determine the mass of a particular volume of a substance?
To determine the mass of a particular volume of a substance using density, you would multiply the density of the substance by the volume of the sample. The resulting value would give you the mass of the substance based on the known density and volume relationship (mass = density x volume).
Will diffrent volumes of the same substance have the same density or different densities?
Different volumes of the same substance will have the same density. Density is an intrinsic property of a substance, which means it is constant regardless of the volume it occupies. This relationship is expressed by the formula density = mass/volume.
Does density change if the sample of the same matter is larger?
No density if a characteristic of matter. Density can vary with temperature and pressure, but a chunk of something twice the volume of another chunk of the same substance will weigh twice as much because the two chunks have the same density.
Does each sample occupies space?
Yes, each sample of a substance occupies space due to its physical dimensions and the volume it occupies in a container. The amount of space a sample occupies is known as its volume.
What is the eqyaion for density?
Density of a substance = (mass of a sample of it)/(volume of the same sample)
How would you calculate the density of a substance?
Density = Mass/Volume so you need to measure the mass of the substance and divide by the volume that it occupies.
How do you calculate density using a formula?
Density of a substance = (mass of a sample of the substance) divided by (volume of the same sample)
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.
What is the ratio of the mass of a sample of substance to its volume?
its density
How do explain volume in mass?
You cannot. Volume it the amount of space a substance occupies, mass is the amount of substance there is. Combining them will give you the density of the substance.
How do you calculate the density of a substance?
The density of a substance is calculated by dividing its mass by its volume. The formula for density is: Density = Mass / Volume. This calculation gives you a measure of how tightly packed the molecules are in a given sample of the substance.
What is the mass of a sample divided by its volume?
Its density. Density is mass per unit volume.
How do you calculate the density of dextrose?
The density of any substance can be easily calculated knowing that it is defined as the ratio of the mass of a substance divided by the volume it occupies.
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).
How does the volume and density of a substance change when it is heated?
When a substance is heated, its volume generally increases due to thermal expansion. On the other hand, the density of the substance usually decreases since the same amount of matter now occupies a greater volume.
