What is the typical density of a rock?

The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn’t as complex as you may think because water’s density is 1 gram per cubic centimeter or 1 g/cm3….Rock Densities.

Rock	Density
Slate	2.7–2.8

What is the highest density rock?

The heaviest rocks would be those that are made up of dense, metallic minerals. Two of the heaviest or densest rocks are peridotite or gabbro. They each have a density of between 3.0 to 3.4 grams per cubic centimeter. Interestingly, peridotite are the rocks that naturally occurring diamonds are found in.

How do you find the density of a mineral sample?

Measure density by dividing the mass or weight of a sample by its volume. Written out, the formula for calculating density is: D = M/V, where D = density (g/mL), M = mass (g), and V = volume (mL). Record the density of each sample on your chart in grams per milliliter (g/mL).

How do you measure the specific gravity of a rock?

Divide the mass of the rock by its volume to calculate the density of the rock. In our example, the density is 20.4/8 = 2.55 g/cubic cm. Divide the rock density by the density of water to calculate the specific gravity.

What is the density of calcite?

Calcium carbonate

Which igneous rock has highest density?

The correct answer is Basalt.

What is the density of a felsic rock?

where the density of water = 1,000 kg/m (or 1 g/cm ). Parameters used to define density and their associated units are summarized below….Composition.

Igneous Rock Type	% Silica (SiO )	Density
Felsic	65% <	Lowest
Indermediate	55% – 65%	Moderate
Mafic	45% – 55%	High
Ultramafic	< 45%	Highest

What is the density of a mineral?

The density of a mineral is the ratio of its mass to its volume. It is a measure of how much “stuff” is squeezed into the amount of space the mineral occupies. Objective: Students will measure and compare the densities of minerals.

Are felsic rocks less dense?

Felsic magma is less dense and more viscous than mafic magma. Felsic rocks tend to be lighter in color compared to mafic rocks. Mafic rocks have higher concentrations of iron and magnesium, while felsic rocks have higher concentrations of aluminum and potassium.

Why do felsic rocks have low grain densities?

Because grain density is affected largely by a rock’s mineral composition and porosity, rocks rich in felsic minerals tend to have lower densities than rocks rich in mafic minerals.

What is a felsic rock?

Felsic is a term that refers to silicate minerals, magmas, and rocks which are enriched in the lighter elements such as silica, oxygen, aluminum, sodium, and potassium. The term combines the words ” feldspar ” and ” silica .”

How to find the density of ethanol?

When producing ethanol, one has to keep a tab on its density as well as water content. How to Find the Density? The mathematical formula to measure the density is p = m / v, wherein p refers to density, m refers to mass, and v refers to volume. You can also measure the density of ethanol using an alcohol monitoring system.
