# The mass of rock is 2.4 kg anf its volume is 950 cm^3 .

• r-soy
In summary, the density of the rock is approximately 0.0025 kg/cm^3, determined by dividing its mass by its volume. The mass was determined using a balance or scale, which measures the gravitational force exerted on an object. The volume can be measured in other units but must be converted correctly for accurate calculations. The density of this rock is less dense than the average of most rocks, which is around 2.65 g/cm^3. The density of a rock is not a constant value and can change depending on external factors such as temperature and pressure.

looks good to me..

sure ?

yes ... your calculations look correct too

I can confirm that the density of the rock is 2.53 g/cm^3 (a) and 2530 kg/m^3 (b). Density is calculated by dividing the mass by the volume, and in this case, the mass of the rock is 2.4 kg and its volume is 950 cm^3. This calculation results in a density of 2.53 g/cm^3, which means that for every cubic centimeter of the rock there is 2.53 grams of mass. Similarly, converting the volume to meters cubed (0.000950 m^3) and dividing it by the mass (2.4 kg) gives a density of 2530 kg/m^3, which means that for every cubic meter of the rock there is 2530 kilograms of mass. These values can be used to further analyze the properties and composition of the rock.

## 1. What is the density of the rock?

The density of the rock can be calculated by dividing its mass (2.4 kg) by its volume (950 cm^3). This gives a density of approximately 0.0025 kg/cm^3.

## 2. How was the mass of the rock determined?

The mass of the rock was most likely determined using a balance or scale, which measures the gravitational force exerted on an object. This force is directly proportional to the mass of the object.

## 3. Can the volume of the rock be measured in other units?

Yes, the volume of the rock can be measured in other units such as liters, cubic meters, or cubic inches. However, it is important to convert the units correctly in order to accurately calculate the density.

## 4. How does the density of this rock compare to other types of rocks?

The density of rocks can vary significantly depending on their composition and structure. However, the average density of most rocks is around 2.65 g/cm^3, making this rock relatively less dense than the average.

## 5. Is the density of this rock a constant value?

No, the density of a rock can change depending on external factors such as temperature and pressure. For example, if the rock is heated, it may expand and become less dense. Additionally, if the rock is compressed, it may become more dense.
