Answer:

Percent composition of #"N"# is #35%#.

Percent composition of #"H"# is #5%#.

Percent composition of #"O"# is #60%#.

Explanation:

#2xx14"g"+4xx1"g"+3xx16"g"=80"g"#

The mass of 1 mol of #"NH"_4"NO"_3# is #80"g"#.

#2xx14"g"=28"g"#

The mass of #"N"# is #28"g"#.

Percent composition of #"N"# is #frac{28"g"}{80"g"}xx100% = 35%#.

#4xx1"g"=4"g"#

The mass of #"H"# is #4"g"#.

Percent composition of #"H"# is #frac{4"g"}{80"g"}xx100% = 5%#.

#3xx16"g"=48"g"#

The mass of #"O"# is #48"g"#.

Percent composition of #"O"# is #frac{48"g"}{80"g"}xx100% = 60%#.
