Answer:
See below in bold.
Explanation:
Nitrogen, Hydrogen and Oxygen are the elements present in ammonium nitrate.
The Molar Mass = 2N + 4H + 3 O
= 2*14.007 + 4*1.008 + 3*15.999
= 80.043.
Percentage of Nitrogen = (2 * 14.007) * 100 / 80.043
= 35.00 %.
Percentage of Hydrogen = (4* 1.008) * 100 / 80.043
= 5.04%.
Percentage of Oxygen = (3 * 15.999) * 100 / 80.043
= 59.96 %.

Answer:
Molecular
Explanation:
Using the rules for the nomenclature for naming binary covalent (molecular) compounds, the compound SO3 is named sulfur trioxide. The prefix tri- indicates that the oxygen has a subscript of 3 and that a molecule of sulfur trioxide has three oxygen atoms.
