The molar mass of silver nitrate (AgNO3) is calculated by adding together the atomic masses of its constituent elements: silver (Ag), nitrogen (N), and oxygen (O).
First, we look up the atomic masses:
- Silver (Ag) = 107.87 g/mol
- Nitrogen (N) = 14.01 g/mol
- Oxygen (O) = 16.00 g/mol
Silver nitrate consists of one silver atom, one nitrogen atom, and three oxygen atoms. Therefore, the molar mass can be calculated as follows:
Molar mass of AgNO3 = (1 × 107.87) + (1 × 14.01) + (3 × 16.00)
Calculating this gives us:
Molar mass = 107.87 + 14.01 + 48.00 = 169.88 g/mol
Thus, the molar mass of silver nitrate is approximately 169.88 g/mol.
