obviously something but not known what!
What makes up 60 percent of 10-20-10 fertilizer?
nitrogen phosphorus potassium
How do you convert percent weight to percent volume for soil and bentonite mix?
You cannot without information on the densities of the two substances.
How does one prepare 95 percent of ethanol from 100 percent?
Find the volume of the 100% ethanol Add 1/19 of water to the volume (if it is like 190ml, add 10ml of water since 190/200=95%)
Percent of Earth's crust is made up of magnesium using volume?
Magnesium makes up about 2% of the Earth's crust by volume. It is the eighth most abundant element in the Earth's crust.
What percent of the makeup of the earth is the crust?
The crust comprises less than 1% of the Earth's total volume.
What 8 minerals make up 98 percent of the Earth's crust?
The 8 minerals that make up 98 percent of the Earth's crust are oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium.
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 can iron be 5.63 percent by mass but only 0.49 percent by volume in the crust?
The difference in mass and volume percentages of iron in the Earth's crust is due to the fact that iron has a higher average density compared to the other components present in the crust. This results in a higher mass percentage of iron relative to its volume percentage. So, even though iron is only 0.49% by volume, its higher density contributes to it being 5.63% by mass in the crust.
How many elements are found in 99 percent of Earth's crust?
Eight elements are found in 99% of Earth's crust: oxygen, silicon, aluminum, iron, calcium, sodium, magnesium, and potassium.
What percent of the earth is radioactive?
Approximately 80% of the Earth's natural radioactivity comes from the decay of uranium, thorium, and potassium-40 in the Earth's crust.
What percentage of the earths mass does the crust make up?
The Earth's crust is approximately 1.65 % of the total volume of Earth.Volume of sphere = 4/3 * pi * r^3Volume of earth = 4/3 * pi * 6,360^3Volume of earth (km3) = 1.078x1012Crust is on average 35 km thick.Therefore radius of earth without crust = 6,360 - 35 = 6,325 km.Volume of earth (not including crust) = 4/3 * pi * 6,325^3 = 1.06x1012 km3Volume of crust = Total volume of earth - Volume of earth (not including crust).Volume of crust = 1.77x1010 km3Percentage of earth's total volume taken by crust = (1.77x1010 / 1.06x1012) * 100Percentage of earth's total volume taken by crust = 1.641 %
What are some uses for potassium?
its found in the earths crust.
What minerals is 99 percent of the Earth's crust made of?
Silicon and oxygen are the most abundant minerals in the Earth's crust, comprising about 99 percent of its composition. Other common minerals found in the Earth's crust include aluminum, iron, calcium, sodium, and potassium.
What is the thinnest and has the least volume crust or outer core?
Crust.
What is the percent composition of potassium in potassium iodide Kl?
The percent composition of potassium in potassium iodide (KI) is 58.5%. This is calculated by dividing the atomic mass of potassium by the molar mass of KI and multiplying by 100.
