Detailed Explanation of Key Factors:
- Molecular Weight Calculation:
- The molecular weight is the sum of the atomic weights of all atoms in the compound. For example, for calcium chloride (CaCl₂): Molecular Weight=1(Ca)+2(Cl)=40.08+2(35.45)=110.98 g/mol\text{Molecular Weight} = 1(\text{Ca}) + 2(\text{Cl}) = 40.08 + 2(35.45) = 110.98 \, \text{g/mol}Molecular Weight=1(Ca)+2(Cl)=40.08+2(35.45)=110.98g/mol
- Atomic Weights:
- Calcium (Ca): 40.08 g/mol
- Chlorine (Cl): 35.45 g/mol
- Carbon (C): 12.01 g/mol
- Oxygen (O): 16.00 g/mol
- Nitrogen (N): 14.01 g/mol
- Hydrogen (H): 1.008 g/mol
- Phosphorus (P): 30.97 g/mol
- Sulfur (S): 32.07 g/mol
- Fluorine (F): 18.998 g/mol
- Common Applications:
- Calcium Chloride: Widely used for melting ice on roads, dust control, and in concrete mixtures. It is also used as a food additive and in water treatment.
- Calcium Carbonate: Found in rocks and shells, it is commonly used as an antacid, in dietary supplements, and as a building material in cement and lime.
- Calcium Hydroxide: Also known as “slaked lime,” it is used in agriculture to raise soil pH, in water treatment, and as a building material.
- Calcium Nitrate: Primarily used in fertilizers for its nitrogen and calcium content, and in waste treatment processes.
- Environmental and Biological Importance:
- Calcium Phosphate is a critical component of bones and teeth and is used in medical applications for bone grafting.
- Calcium Oxide (Lime) is crucial in industrial processes like steel manufacturing, where it removes impurities from the metal.
Practical Uses of Molecular Weight:
- Industrial Chemistry: Knowing the molecular weight helps in determining the quantities needed for reactions, as well as dosing for applications in agriculture, pharmaceuticals, and construction.
- Medicine: Calcium compounds are used in various treatments, such as calcium acetate for controlling phosphate levels in kidney disease patients.
- Environmental Science: Calcium hydroxide is used for water and wastewater treatment by neutralizing acidity and removing contaminants.
