Aluminum is widely distributed throughout the world in the form of aluminosilicates. The property of these minerals prevents them from being a source of aluminum
Aluminum, silicon, and oxygen are the main elements found in aluminosilicate minerals, which have the IMA symbol Als. They make up a sizable portion of the minerals in kaolin and other clays.
Because some aluminosilicates' chemical compositions contain water, they have a clay-like consistency and can be utilized as thickeners, lubricants, and clay substitutes. Other, more crystalline aluminosilicates can be used to make glass, gemstones, industrial abrasives, and abrasives.
A hydrated aluminosilicate mineral called zeolite has a structure that is defined by connected tetrahedra, each of which has four oxygen atoms surrounding a silicon or aluminum cation.

10% solution means=
=
= 100 mg/mL
If the dentist inject 0.3 mL, that is equal to 0.3× 100 mg.
If the dentist inject 0.3 mL, that is equal to 30 mg.
So, as anesthetic procaine hydrochloride is often used to deaden pain during dental surgery. the compound is packaged as a 10.% solution (by mass; d = 1.0 g/ml) in water. When our dentist
injects 0.30 ml of the solution, 30 mg of procaine hydrochloride (in milligrams) is injected.
It is approximately 400 - 700 nanometres.
Hope this helps.
