The molar mass of KNO3 (Potassium Nitrate) is calculated by adding the atomic masses of its constituent elements: Potassium (K), Nitrogen (N), and Oxygen (O).
– The atomic mass of Potassium (K) is approximately 39.1 g/mol.
– The atomic mass of Nitrogen (N) is approximately 14.0 g/mol.
– The atomic mass of Oxygen (O) is approximately 16.0 g/mol. Since there are three oxygen atoms in KNO3, we multiply 16.0 by 3, which gives us 48.0 g/mol.
Now, we add these values together:
39.1 (K) + 14.0 (N) + 48.0 (O) = 101.1 g/mol.
Therefore, the molar mass of KNO3 is 101.1 g/mol.
