How do you calculate the molar mass for KN03
To calculate the molar mass of KNO3 (potassium nitrate), you need to find the atomic masses of each element in the compound and then add them up.
The atomic masses are:
- K (potassium) = 39.10 g/mol
- N (nitrogen) = 14.01 g/mol
- O (oxygen) = 16.00 g/mol
Now, you can calculate the molar mass of KNO3:
Molar mass of KNO3 = (1 * atomic mass of K) + (1 * atomic mass of N) + (3 * atomic mass of O)
Molar mass of KNO3 = (1 * 39.10) + (1 * 14.01) + (3 * 16.00)
Molar mass of KNO3 = 39.10 + 14.01 + 48.00
Molar mass of KNO3 = 101.11 g/mol
Therefore, the molar mass of KNO3 (potassium nitrate) is 101.11 g/mol.
