H=1. To minimize errors due to rounding off numbers, keep as many significant figures in the calculations as possible.
N=16. Thus, you would need to look up or recall the molar masses of these compounds. Perhaps you were asking how much nitrogen is in 4.444 moles of ammonium sulfide given the percent of nitrogen in any given mass. You can write the percent composition of nitrogen in ammonium sulfate by dividing the molar mass of the two nitrogen atoms by the molar mass of the compound, and multiplying the result by 100. Determine the percent composition for ammonium phosphate, (NH 4) 3 PO 4, a compound that is used as a fertilizer.
#O ~~ 15.999 " amu"#, #(NH_4)_2SO_4 = 2*(14.007+4*(1.0079))+32.065+4*15.999#
:) -Little Miss … Here is how to determine the percent composition for a compound.
Therefore, the percent by mass of sulphur in ammonium sulphate is 100(32.06/132.13) or 24.26, to the justified number of significant digits.
#(2 * 14.007color(red)(cancel(color(black)("g/mol"))))/(132.14color(red)(cancel(color(black)("g/mol")))) * 100 = color(green)("21.2%")#.
Determine the percent composition for ammonium phosphate, (NH4)3PO4, a compound that is used as a fertilizer. #S ~~ 32.065 " amu"# Relevance. Note that the sum of the percentages is 100%, http://nobel.scas.bcit.ca/wiki/index.php?title=Percent_composition_of_compounds&oldid=2980.
There is said to be about 600 grams of nitrogen in 1.00 pound of ammonium and 130 pounds of phosphorus available in 1.00 pounds of ammonium phosphate. #N ~~ 14.007 " amu"# So, the molar mass of ammonium sulfate is 132.14 g/mol and the molar mass …
So, the molar mass of ammonium sulfate is 132.14 g/mol and the molar mass of nitrogen is 14.007 g/mol. To get the percent composition of nitrogen is ammonium sulfate, #(NH_4)_2SO_4#, you need to know the molar mass of the compound and that of elemental nitrogen. 10 years ago. Awesomeness. 8804 views #-> 21.2%# since it is #(NH_4)_2# and thus there are two #N# atoms in there. Total mass of ammonium chloride=14+[1*4]+35.5 =53.5 % of nitrogen=mass of nitrogen in compund----- *100. total mass of compund =14/53.5 * 100 =26.168 g =26.17 g. Source(s): Happy to help! Therefore, the percent by mass of nitrogen in ammonium nitrate is: 100[(2)(14.0067)/80.04] or 35.00 %, to the justified number of significant digits.

Take a look at a sample calculation.
The proportion by mass of each element in a compound is called percent composition. This page was last edited on 16 June 2012, at 19:44.

Percent of nitrogen: 21.2% To get the percent composition of nitrogen is ammonium sulfate, (NH_4)_2SO_4, you need to know the molar mass of the compound and that of elemental nitrogen.
Percentage of nitrogen in ammonium nitrate can be determined as follow: Molecular mass of ammonium nitrate(NH4NO3) = 14g + 4×1g + 14g + 3×16g = 80g So in 80 g of NH4NO3, mass of nitrogen is= 14 +14 = 28g So in 1 g of NH4NO3, mass of nitrogen is =28/80 In 100 g of NH4NO3, mass of nitrogen is =28×100/80 = 35% So percentage of nitrogen in ammonium nitrate is 35%.
Ammonia,NH3 ; ammonium nitrate,NH4NO3 ; and ammonium hydrogen phosphate (NH4)2HPO4, , are all common fertilizers. Rank the compounds in order from largest mass percent of nitrogen to smallest mass percent of nitrogen.
