Understanding the Molecular Weight of Sodium Thiocyanate
Sodium thiocyanate, chemically represented as NaSCN, is a versatile compound widely used in various industrial applications. It is a white, crystalline substance with a characteristic solubility in water, which makes it valuable in a range of chemical processes. One of the fundamental properties of sodium thiocyanate is its molecular weight, a critical factor in understanding its chemical behavior and applications.
The molecular weight of sodium thiocyanate can be determined through the summation of the atomic weights of its constituent elements sodium (Na), sulfur (S), carbon (C), and nitrogen (N). The atomic weight of sodium is approximately 22.99 g/mol, sulfur is around 32.07 g/mol, carbon is about 12.01 g/mol, and nitrogen is roughly 14.01 g/mol. Therefore, the molecular weight of NaSCN can be calculated as follows
- Sodium (Na) 22.99 g/mol - Sulfur (S) 32.07 g/mol - Carbon (C) 12.01 g/mol - Nitrogen (N) 14.01 g/mol
Adding these values together results in the molecular weight of sodium thiocyanate
\[ \text{Molecular Weight of NaSCN} = 22.99 + 32.07 + 12.01 + 14.01 = 81.08 \, \text{g/mol} \]
