Because iron is dense - a small volume or amount weighs a lot compared to other materials.

Is the earths crust less than one percent of earths mass?
With a very sizable iron core and a (by comparison) wafer-thin crust, I doubt that the earth's crust even approximates a full percentage point.
About 75 by mass of Earth's crust is composed of what two elements?
About 75 percent of the weight of the Earth's crust is made up of Oxygen and Silicon. The remaining percentage is composed of Aluminum, Iron, Calcium, Sodium, Potassium, and Magnesium.
What is the most common substance on earth is water?
That depends in part on what you mean by "substance", and whether you measure by volume, by mass, or by number of moles! The most common elements (water is not an element) in the Earth's crust (atmosphere, oceans, land, up to a depth of a few kilometers), by mass, are oxygen, silicon, and aluminium - in that order.
What makes up 2.83 percent of the Earth's crust?
The 2 types of the Earth's crust are the ContinentalCrust and the Oceanic Crust. The Continental Crust is made of granite and the Oceanic crust is made of basalt.
How do you calculate the percent chloride with the volhard method?
(mass /volume)x100
What is the formula of the percent of volume and percent of mass?
% of volume = 100*(volume of substance that you are interested in)/(total volume) % of mass = 100*(mass of substance that you are interested in)/(total mass).
Is the earths crust less than one percent of earths mass?

What percent of earth's mass is crust?
About 2%
What is the difference of percent of mass and percent of volume?
Percent of an objects mass is expressed in terms of its weight. Percent of an objects volume is expressed in terms of its size.
Why is steel denser then iron?
Density is mass divided by volume. If we assume the mass of the iron and the cotton is the same, you will find that the iron will occupy less space (less volume) than that of the cotton. The value of a mass divided by a small volume is higher than the value of the same mass divided by a larger volume. If we assume the volume of both the iron and the cotton is the same, you will also find that the mass of the iron will be higher than the mass of the cotton. The value of a large mass divided by a volume is larger than the value of a small mass divided by the same volume. In both assumptions, the value of mass divided by volume for the iron is higher than the value of mass divided by volume for the cotton. Since density is mass divided by volume, the density of iron is therefore higher than the density of cotton.

Which layer of the earth is 1 percent of the earth's mass?
The Earths crust.
What is percent by mass over volume?
Density
How much does iron weigh?
A single iron atom weighs 55.845 atomic mass units.The weight of a quantity of pure iron will vary depending on the volume and gravitational acceleration. The mass of iron will also vary depending on the given volume. Given the density at room temperature, 7.874 g·cm−3 and the volume of iron, you can find the mass by multiply the density and the volume. To find the weight of an object, you would need to multiply its mass by the local gravitational acceleration.
What is the percent composition by mass of 10.5g of Fe?
Pure iron is 100% iron.
How much iron will be present in one molecule of hemoglobin if hemoglobin has 0.25 percent by mass iron and the molecular mass of hemoglobin is 89600u?
If a quarter of the mass of the molecule is iron and the mass of the molecule is 89600u, then the mass of iron is 22400u ... a quarter of the total mass.
