What is the density of a mineral sample with a mass of 20g and a volume of 12cm3?
The density of the mineral sample is 1.67 g/cm3. This is calculated by dividing the mass (20g) by the volume (12cm3).
How did early prospectors use density to determine whether they had found gold or pyrite?
Early prospectors used density to determine whether they had found gold or pyrite by comparing the weight of the mineral sample to its volume. Gold has a higher density than pyrite, so a sample of gold would feel heavier for its size compared to a sample of pyrite. By calculating the density of the sample using the formula density = mass/volume, prospectors could determine if they had found gold or pyrite based on the density value obtained.
What is the following is a quantitative property of minerals?
Density is a quantitative property of minerals that can be measured by determining the mass of a mineral sample and dividing it by its volume.
A one gram sample of hematite takes up more space than a one gram sample of malachite what mineral is this?
The mineral is hematite. Hematite has a higher density compared to malachite, so even though they both weigh the same (one gram in this case), hematite will take up more space due to its higher density.
How do you find the density of an unknown mineral?
To find the density of an unknown mineral, you can measure its mass using a scale and then measure its volume by displacement in water. Divide the mass by the volume to calculate the density of the mineral.
Is it true that the larger the sample of a mineral the greater its density?
No, the density of a mineral remains constant regardless of the size of the sample. Density is an intrinsic property of the mineral and is determined by its composition and structure. It is typically expressed in units of mass/volume, so a larger sample will have a proportionally greater mass and volume, resulting in the same density.
What is the density of a mineral sample with a mass of 20g and a volume of 12cm3?
The density of the mineral sample is 1.67 g/cm3. This is calculated by dividing the mass (20g) by the volume (12cm3).
What equation would you use to express the density of a mineral sample?
density = mass / volume
What property is the mass of a mineral sample per unit volume?
Its density.
Is the density of a mineral considered its mass divided by its volume?
Yes, the standard definition of density is mass divided by volume. This presumes the mineral is uniform throughout the sample.
How can density help identify a mineral?
Each mineral has a characteristic density (or range of densities), so if the measured density is a close match to a mineral you know, it MAY be that mineral; if it doesn't match, it is something different.
How are the characteristics of a mineral identified?
Through testing of a sample to determine hardness, luster, streak, density, and chemical composition.
What is the mineral property defied by Density of the mineral sample divided by the density of water?
The mineral property defined by the ratio of a mineral's density to the density of water is called specific gravity. It is a useful parameter for identifying minerals and can help distinguish between different types of minerals based on their mass-to-volume ratio. Specific gravity is a dimensionless quantity that quantifies how much denser or lighter a mineral is compared to water.

What is the eqyaion for density?
Density of a substance = (mass of a sample of it)/(volume of the same sample)
