(a) Interpretation: Percentage of the overall molar mass of the compound that is represented by the negative ions in ammonium sulfide should be calculated. Concept introduction: Percent composition defined as the relative amounts of each element present in a compound and is defined as mass of the element in 1 mole of the compound divided by the molar mass of the compound multiplied by 100. Mass of an element can be obtained by multiplying the atomic weight of the element with the number of that particluar element present in the compound. Whereas, molar mass is obtained by adding up all the masses of elements in the compound.
