To calculate the molar mass of , we need to find the atomic masses of each element in the compound and multiply them by their respective subscripts.The atomic masses are:- Potassium (K): 39.10 g/mol- Aluminum (Al): 26.98 g/mol- Sulfur (S): 32.07 g/mol- Oxygen (O): 16.00 g/mol- Hydrogen (H): 1.01 g/molNow, let's calculate the molar mass of each part of the compound:- : - Potassium (K): g/mol - Aluminum (Al): g/mol - Sulfur (S): g/mol - Oxygen (O): g/mol - Total: g/mol- : - Hydrogen (H): g/mol - Oxygen (O): g/mol - Total: g/molFinally, add the molar masses of both parts: g/molTherefore, the correct answer is:d.
