Answer 2

To find the molar mass of FeS (Iron sulfide), you need to add up the molar masses of its constituent elements: iron (Fe) and sulfur (S).

Given: molar mass of sulfur (S) = 32 g/mol molar mass of iron (Fe) = 56 g/mol

Now, to find the molar mass of FeS: molar mass of FeS = molar mass of Fe + molar mass of S molar mass of FeS = 56 g/mol + 32 g/mol molar mass of FeS = 88 g/mol

So, the molar mass of FeS is 88 g/mol.
