The density is 10.7 g/mL. The sample is not pure lead because the density of pure lead is 11.3 g/mL.

What is the mass of a sample divided by its volume?
Its density. Density is mass per unit volume.
Density can be determined using the formula?
I have no clue. Sorry. :( ^^ Ignore that ^^ I think Density = mass/volume.
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 density is the criteria for purity with respect to chemistry?
Mass and volume are extensive properties, which are dependent upon the size of the sample. A larger sample will have a greater mass and volume than a smaller sample. Density is an intensive property, which does not depend on the size of the sample. Density is a ratio of mass to volume, which does not vary with the size of the sample. The density of a larger sample will be the same as the density of a smaller sample.
Why is the density of a substance independent of sample size?
Density is an intensive quantity which means it is independent of size. This can be seen from the definition of density. Density = mass/volume So if the sample size increases than so does the mass, but the density remains unchanged.
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 density of a sample of ore that has a mass of 62 g and occupies 21.9 cm3 (round to the nearest tenths)?
density = mass / volume = 62g / 21.9 cm³ ≈ 2.8 g/cm³
What is the mass of a sample divided by its volume?
Its density. Density is mass per unit volume.
What is the eqyaion for density?
Density of a substance = (mass of a sample of it)/(volume of the same sample)
Measurement of the amount of space that matter occupies?
Volume is a measure of how much space a sample of matter occupies. the SI unit of volume is m3 .
If a sample of gas occupies 20 ml at -132 C what volume does the sample occupy at 50 C?
280 ml
What is the density of a sample that has mass of 77.0 g and a volume of 36 mL?
The density of the sample is about 2.14 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)

How does halving the sample affect the density?
Not at all. The density remains the same.
