please answer it quickly​

Answer 1

Answer:

The answer is NH3.

Explanation:

Using the table method to calculate Empirical Formula:

Ele. %. At. Mass. At. Ratio. Simplest Ratio

1. N. 82.35. 14. 6. (approx) 3 (approx)

2. H. 17.64. 1. 17.64. 1

Hence the empirical formula contains 1 atom of Hydrogen and 3 atoms of Nitrogen

Thus, the formula is:

NH3

Answer 2

As given, the mass of nitrogen and hydrogen such as,

(N=14,H=1)

Number of a mole of nitrogen= 82.35 = 5.88

14

Number of a mole of hydrogen=17.64 = 17.64

1

the ratio of their moles is 5:88 : 17:64

1:3

Thus, the empirical formula is NH3
