Answer:- The molar mass of potassium sulfide is 110.26 grams per mole. So, 3.3 moles of potassium sulfide would have a mass of 363.82 grams.
To calculate the mass of 3.3 moles of potassium sulfide, we can use the following equation:
Mass = Moles * Molar mass
Mass = 3.3 moles * 110.26 grams/moles
Mass = 363.82 grams
