Percent by mass of ammonium nitrate

Asked by maham237 @ in Chemistry viewed by 255 People

Calculate the percent by mass of each element in
ammonium nitrate (NH4NO3).
The first step is to calculate the molar mass of
ammonium nitrate.
What elements are present in ammonium nitrate?

Answered by maham237 @


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 %.
