What is Earth’s average density?
5.51 g/cm³Earth / Density
How do you find density in kg m3?
How do I find density?
- Measure the object's mass (or weight) in kilograms.
- Measure the volume of the object in m³.
- Divide the mass by the volume.
- You will then have the density of the object in kg/m³.

What is the average density g cm3?
Given the mass of Earth is 5.972 × 1024 kg, we can divide by its volume as noted above. After converting kilograms and cubic kilometers to grams and cubic centimeters, Earth density is about 5.519 g/cm3. And this roughly checks in with the general consensus of Earth density at about 5.513 g/cm3.
What is the density of the Earth in SI units?
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. Density can also be expressed as kilograms per cubic metre (in metre-kilogram-second or SI units).
What is the average density of the Earth Class 9?
Hence, the average density of the earth in terms of g, G and R is 4πGR3g.
How do you find average density?
- The average density of an object equals its total mass divided by its total volume.
- Calculating the average density of a mixture is done by multiplying the densities of each compound by the volume of the respective compound then dividing the result by the sum of all of the volumes.

How do I calculate the average?
Average This is the arithmetic mean, and is calculated by adding a group of numbers and then dividing by the count of those numbers. For example, the average of 2, 3, 3, 5, 7, and 10 is 30 divided by 6, which is 5.
What is the average density of water?

How many kg is 1m3 of sand?
Average density of sand is 1620 kg/m3, it means 1620 kg sand occupy 1 cubic metre of space or container, 1 cubic meter sand weight = 1620kg, so 1620kg is weight of 1 cubic meter sand.
How many kg is a cubic meter of soil?
1 cubic meter of soil = 1602.8 kilograms = 1.6 tons.
What is the average density of population in India?
The population density of India in 2011 was 382 per sq km-decadal growth of 17.72 percent.
Does density depend on g?
Does density depend on gravity? No, it depends on mass and volume only.
How do you solve for average density?
- The average density of an object equals its total mass divided by its total volume.
- Calculating the average density of a mixture is done by multiplying the densities of each compound by the volume of the respective compound then dividing the result by the sum of all of the volumes.
Why do we calculate average?
The average is used to represent one single value for a given set of quantities. Further, it is always difficult to represent all the observations, and hence the average of the observations is taken to represent all the observations.
What are the 3 ways to calculate average?
There are three main types of average: mean, median and mode. Each of these techniques works slightly differently and often results in slightly different typical values. The mean is the most commonly used average. To get the mean value, you add up all the values and divide this total by the number of values.
What is the density of water in kg/m 3?
1000 kg/m3 Water density is rounded to 1000 kg/m3 in SI unit or 1 g/cm3 in CGS unit unless you need an exact value or are inclined towards the accuracy of conducting a lab or any other Science experiment in extreme temperatures.
How do you find the average of density?
Calculating the average density of a mixture is done by multiplying the densities of each compound by the volume of the respective compound, then dividing the result by the sum of all of the volumes.
How many kg is 1m3 of cement?
Equals: 1,505.74 kilograms (kg – kilo) in mass.
How many kg is 1m3 of concrete?
One cubic metre of concrete weighs 2.5 Tonnes. Typically, 1m3 of concrete is made up of 350Kg of cement, 700Kg of sand, 1,200Kg of chippings and 150 Litres of water.
What does 1 cubic meter of earth weigh?
How much does 1 cubic meter of soil weight? 1 cubic meter of soil = 1602.8 kilograms = 1.6 tons.
How do you calculate m3 of soil?
Conversion of 6×4 trailer load to cubic metres If you are not sure how much soil you will need for the job, using big strides, pace out the length and the width of the area in question. When you have this multiply the length by the width and multiply by the required depth.
What is the density of Pakistan?
287 per Km2 Pakistan ranks number 5 in the list of countries (and dependencies) by population. The population density in Pakistan is 287 per Km2 (742 people per mi2).
What is the average density of population in?
India's average density of population has increased to 419.80 people per square km. The population of India represents more than one-seventh of the total world's population.
What is the value of g’on Earth?
9.8 m/s2 The acceleration due to gravity on Earth or the value of g on Earth is 9.8 m/s2. Which implies that, on Earth, the velocity of an object under free fall will increase by 9.8 every second. This acceleration is due to the Earth's gravity.
How is g calculated?
The acceleration g=F/m1 due to gravity on the Earth can be calculated by substituting the mass and radii of the Earth into the above equation and hence g= 9.81 m s-2.
What is the formula of density of Earth?
Hence, the average density of the earth in terms of g, G and R is 4πGR3g.
