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 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 numbers
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 atoms for the compound NaCl?
The ratio Na/Cl is 1 in the formula unit.
What is the ratio of atoms in a carbohydrate?
All sugars are carbohydrates, with the general ratio Cx(H2O)y. There are thus 2 moles of H atoms to 1 mole of C atoms.
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 compound ratio of P2O5 of phosphorus atoms to oxygen atoms?
This ratio is 2/5.
True or false Granite can be pink or black depending on the ratio of feldspar mica and quartz?
True!
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 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 atoms in monosaccharides?
The ratio of atoms in monosaccharides is 1 carbon: 2 hydrogen: 1 oxygen.
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.
What is the ratio of the number of oxygen atoms to carbon atoms in the graphite oxide?
The ratio (as atoms) carbon/oxigen in graphitic oxides is between 2,1 and 2,9.
What is the ratio of sodium atoms to chlorine atoms?
2:4
What is the ratio of sodium atoms to oxygen atoms?
1:1
What is the ratio of atoms in Co2?
C to O in the ratio 1 : 2.
What determines what type of feldspars will form?
The type of feldspar that forms depends on which metal combines with the silicone and oxygen atoms.
