Ionic compounds generally form between elements that are metals and elements that are nonmetals. For example, the metal calcium (Ca) and the nonmetal chlorine (Cl) form the ionic compound calcium chloride (CaCl2). In this compound, there are two negative chloride ions for each positive calcium ion
Answer : The percentage (by mass) of 
in the mixture is 20 %
Explanation :
As we are given that, 10 % sulfur by mass that means 10 grams of sulfur present in 100 grams of mixture.
Mass of sulfur = 10 g
Mass of mixture = 100 g
Now we have to calculate the mass of .
As, 32 grams of sulfur present in 64 grams of
So, 10 grams of sulfur present in 
grams of
Thus, the mass of is 20 grams.
Now we have to calculate the percentage (by mass) of in the mixture.
Therefore, the percentage (by mass) of in the mixture is 20 %
