What effect does the amount of the sample of a substance affect its density?
it has no effect. density of a substance is the same no matter the size or shape of the sample.
What is the mass of a sample divided by its volume?
Its density. Density is mass per unit volume.
A sample thought to be pure lead occupies a volume of 15.0 mi.and has a mass of 160.0g.determine the density and is the sample pure lead?
The density is 10.7 g/mL. The sample is not pure lead because the density of pure lead is 11.3 g/mL.
A scientist has analyzed the chemicals that make of a sample of an unknown substance. Which chemicals would be the best indicator that the unknown substance is a plant?
cellulose and starch

What is the density of a 26.5mL sample of an unknown substance that has a mass of 43.54g?
density = mass/volume = 43.54g / 26.5ml ≈ 1.643 g/ml
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)
What is the eqyaion for density?
Density of a substance = (mass of a sample of it)/(volume of the same sample)
Kelly has a sample of an unknown substance. Which properties of the substance will be the same no matter how large or small her sample is?
All intrinsic properties will be the same regardless of sample size. Some examples would be density, color, temperature, chemical reactivity, etc.
What effect does the amount of the sample of a substance affect its density?
it has no effect. density of a substance is the same no matter the size or shape of the sample.
Why is it not necessary to know the volume of a substance when calculating its density?
If you want to CALCULATE the density of an unknown substance, you need to divide its mass by its volume, so you need to measure both first. If it is a homogeneous (uniform) substance, and you can take away a piece, you can take any sample. Any piece of the substance will have the same density.
An 8.192-mL sample of an unknown has a mass of 9.02gWhat is the density of the unknown?
1.10
Is it true that the density of a substance is the same for all samples of the substance?
No, as density also depends on the state of matter in the sample of the substance.
What is the density of a sample of ore that has a mass of 57g and occupies What is the density of a sample of ore that has a mass of 57 g and occupies 29 cm3 Answer in units of g cm3?
Density = mass/volume, So, Density = 57g/29cm3 = 2.0g/cm3* The number on the calculator is 1.965517241, which is rounded to 2.0 because of significant figures.
What is the mass of a sample divided by its volume?
Its density. Density is mass per unit volume.
The density of the substance is the same for all samples of the substance true or false?
Any sample size of a particular substance will have the same density.
What is the ratio of the mass of a sample of substance to its volume?
its density
