Answer 1

Solution:

The highest to lowest percent ratio of nitrogen in the given compounds are:

NH3 > NH4NO3 > (NH4)2HPO4 > (NH4)2SO4 > KNO3 > NH4H2PO4

Explanation:

The molar masses of the compounds are given as,

NH3 = 17 g/mol

NH4NO3 = 80 g/mol

(NH4)2HPO4 = 132.06 g /mol

(NH4)2 SO4 = 132.14 g/mol

KNO3 = 101.1 g /mol

Hence,

Mass percent of nitrogen in NH3 is highest and NH4H2PO4 is smallest.
