Feldspars comprise a group of almost 20 related minerals and the ratio of elements differ from one type to another. The general ratio of atoms in common feldspar molecules is
X:Al:Si:O = 1:(1 or 2):(3 or 2):8
where X can be Na, K, or Ca.
When X is Na or K, then Al = 1 and Si = 3
and when X = Ca, then Al = 2 and Si = 2.

What is the ratio of potassium to aluminum to oxygen in feldspar?
Feldspar is a group of minerals that typically includes potassium feldspar (orthoclase), which has the chemical formula KAlSi3O8. In this formula, the ratio of potassium (K) to aluminum (Al) to oxygen (O) is 1:1:8 when considering the composition in terms of K, Al, and O. This means for every one potassium atom, there is one aluminum atom and eight oxygen atoms in the structure of potassium feldspar. Other feldspar varieties, such as plagioclase, have different ratios.
How many atoms are in one molecule of potassium feldspar?
One molecule of potassium feldspar, which has the chemical formula KAlSi3O8, contains a total of 10 atoms. This includes one potassium (K) atom, one aluminum (Al) atom, three silicon (Si) atoms, and eight oxygen (O) atoms.
What is the ratio of phosphorous atoms to oxygen atoms in the compound?
This ratio is different for each compound; for the oxide P4O10 the ratio is 2/5.
What tells the ratio of atoms?
The ratio of atoms is determined by the chemical formula of a compound. This formula indicates the type and number of atoms present in a molecule. The subscripts in a chemical formula provide the ratio of each type of atom in the compound.
What is the ratio of hydrogen to oxygen in this sample of four water molecules?
2:1 ratio. There would be eight atoms of hydrogen and four atoms of oxygen.
What is the ratio of potassium to aluminum to oxygen in feldspar?

True or false Granite can be pink or black depending on the ratio of feldspar mica and quartz?
True. The color of granite is determined by the presence and ratio of minerals such as feldspar, mica, and quartz. Pink granite typically contains more feldspar, while black granite contains more mica and quartz.
How many atoms are in one molecule of potassium feldspar?
One molecule of potassium feldspar, which has the chemical formula KAlSi3O8, contains a total of 10 atoms. This includes one potassium (K) atom, one aluminum (Al) atom, three silicon (Si) atoms, and eight oxygen (O) atoms.
What is the compound ratio of P2O5 of phosphorus atoms to oxygen atoms?
This ratio is 2/5.
How do you determine the age of a feldspar sample?
Feldspar has 98 atoms of 40Ar every 97 atoms of 40K. 10.9% of 40K decays to 40Ar. t(1/2)=1.25E9 0.693/1.25E9= 567E-10 = K
What is the ratio of potassium atoms to nitrogen?
The chemical formula of potassium nitride is K3N. The ratio potassium atoms/nitrogen atoms is 3.
What is the ratio of phosphorous atoms to oxygen atoms in the compound?
This ratio is different for each compound; for the oxide P4O10 the ratio is 2/5.
What is the ratio of carbon atoms to oxygen atoms in this compound C H O?
The ratio of carbon atoms to oxygen atoms in the compound CH2O is 1:1.
What is the ratio phosphorus atoms to oxygen atoms in the compound?
The ratio of phosphorus atoms to oxygen atoms in a compound can vary depending on the specific compound. For example, in phosphorus pentoxide (P4O10), the ratio is 4:10.
What is the ratio of atoms in monosaccharides?
The ratio of atoms in monosaccharides is 1 carbon: 2 hydrogen: 1 oxygen.
What is the ratio of atoms in NO?
The ratio of atoms in NO is 1 nitrogen atom to 1 oxygen atom.
What is the ratio of atoms?
A chemical formula gives the number ratio of the different kinds of atoms present in the compound. This means that the ratios are the same if you count in individual atoms, dozens of atoms, or molecules of atoms.
