What is the Molecular Weight of CaF₂?
Calcium fluoride (CaF₂) is a widely used compound in various industries, including optics, ceramics, and dentistry. Understanding its molecular weight is crucial for applications in chemistry, materials science, and manufacturing. This blog post will explore the molecular weight of CaF₂, its calculation, and its significance in different fields.
How to Calculate the Molecular Weight of CaF₂
To determine the molecular weight of CaF₂, you need to sum the atomic weights of its constituent elements: calcium (Ca) and fluorine (F).
Step 1: Identify Atomic Weights
- Calcium (Ca): Approximately 40.08 g/mol
- Fluorine (F): Approximately 18.998 g/mol
Step 2: Sum the Weights
CaF₂ consists of one calcium atom and two fluorine atoms. The calculation is as follows:
Molecular Weight = (1 × 40.08) + (2 × 18.998) = 40.08 + 37.996 = 78.076 g/mol
📌 Note: The molecular weight of CaF₂ is 78.076 g/mol, rounded to 78.08 g/mol for simplicity.
