## What is the density of a substance or object?

Density is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water).

## What is density of a substance How is it measured?

Density is calculated by the dividing the mass by the volume, so that density is measured as units of mass/volume, often g/mL. If both water samples are at the same temperature, their densities should be identical, regardless of the samples’ volume.

What is the density of a substance quizlet?

Density is the measure of how much mass is contained in a given volume of a substance. Density= mass/volume or d=m/v. Density is mass divided by volume. You just studied 13 terms!

What is the density of an object and what is an example of density?

The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. For example, the density of water is 1 gram per cubic centimetre, and Earth’s density is 5.51 grams per cubic centimetre.

### What is density the measure of?

Density has the units of mass divided by volume such as grams per centimeters cube (g/cm3) or kilograms per liter (kg/l).

### Which liquid is denser hexane or water?

b; hexane is insoluble in water and less dense than water.

How would you calculate the density of a substance?

Density is calculated by dividing the mass of a substance by the volume (density = mass/volume). If the density of a substance is known, determining the mass of a sample will allow the volume to be calculated.

Which substance has the highest density?

Basalt is the type of rock with the highest density. With an average value around 3 grams per cubic centimeter, it’s not even close to that of the metals, but it’s still heavy.

#### How can density be used to identify a substance?

Density of a substance can be determined by measuring mass and volume. These measurements are used in the formula D= m/v to determine the density of the substance. Density values are useful when trying to identify an unknown substance. Units for density are g/mL and g/cm^3.

#### What does the density tell you about a substance?

Density is the characteristic property of the substance. Density is related to mass and volume of the substance. Explanation: Density of the substance decides whether it will float or submerge in water or any other liquid. If the substance is denser than the liquid then it will sink and if its density is lower than the liquid then it will float. Density is written in kilogram per cubic meter.
