Answer:

Empirical formula is NH₃

Explanation:

Given data:

Percentage of hydrogen = 82%

Percentage of nitrogen  = 18%

Empirical formula = ?

Solution:

Number of gram atoms of H = 18 / 1.01 = 17.8

Number of gram atoms of N  = 82 / 14  = 5 .9

Atomic ratio:

                  H               :         N

              17.8/5.9        :        5.9/5.9

                  3               :        1

H : N = 3:1

Empirical formula is NH₃
