Answer to Problem 2.102P
The molecular formula for ammonium sulfate is
Explanation of Solution
Ammonium and sulfate are polyatomic ions. The formula for the sulfate ion is
While naming compounds containing polyatomic ions, when two or more of the same polyatomic ion are present, the ion appears in parentheses. The total number of the polyatomic ion is written as a subscript outside the parentheses.
In ammonium sulfate, two ammonium polyatomic ions associate with one sulfate polyatomic ion. Hence the molecular formula becomes
The formula to calculate the molecular mass of
Substitute
The molecular formula for ammonium sulfate is
