How do you calculate the molar mass for KN03

Answer 1

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.
