Ammonium thiocyanate, represented by the chemical formula NH4SCN, is a fascinating compound that plays a significant role in various industrial and laboratory applications. Understanding its molecular weight and properties can shed light on its importance in chemical synthesis, agriculture, and analytical chemistry.
The molecular weight of ammonium thiocyanate is calculated from the atomic weights of its constituent elements nitrogen (N), hydrogen (H), sulfur (S), and carbon (C). Specifically, the molecular weight can be derived from the following atomic weights nitrogen (approximately 14.01 g/mol), hydrogen (approximately 1.008 g/mol), sulfur (approximately 32.07 g/mol), and carbon (approximately 12.01 g/mol). Given that ammonium thiocyanate comprises one nitrogen atom, four hydrogen atoms, one sulfur atom, and one carbon atom, the molecular weight can be computed as follows
- Nitrogen 1 × 14.01 g/mol = 14.01 g/mol - Hydrogen 4 × 1.008 g/mol = 4.032 g/mol - Sulfur 1 × 32.07 g/mol = 32.07 g/mol - Carbon 1 × 12.01 g/mol = 12.01 g/mol
By adding these values together, we find that the molecular weight of ammonium thiocyanate is approximately
\[ 14.01 + 4.032 + 32.07 + 12.01 \approx 62.12 \text{ g/mol} \]
