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.

What is the molality of an aqueous KCl solution with a mole fraction of KCl, XKCl = 0.175? (The molar mass of KCl = 74.55 g/mol
NARA [144]

Answer:

The molality of the KCl solution is 11.8 molal

Explanation:

Step 1: Data given

Mol fracrion KCl = 0.175

Molar mass KCl = 74.55 g/mol

Molar mass H2O = 18.02 g/mol

Step 2: Calculate mol fraction H2O

mol fraction H2O = 1 - 0.175 = 0.825

Step 3: Calulate mass of H2O

Suppose the total moles = 1.0 mol

Mass H2O = moles H2O * molar mass

Mass H2O = 0.825 * 18.02 g/mol

Mass H2O = 14.87 grams = 0.01487 kg

Step 4: Calculate molality

Molality KCl = 0.175 / 0.01487 kg

Molality KCl = 11.8 molal

The molality of the KCl solution is 11.8 molal
