What is the empirical formula for a substance if a 201.6 g sample of it contains 54.0 grams of nitrogen, 15.0 grams of hydrogen,
jeyben [28]

The empirical formula of the substance would be  NH_4Cl

<h3>Empirical formula calculation</h3>

The constituents of the compound are as follows:

N = 54/201.6 = 26.78% = 26.78/14 = 1.91 moles

H = 15/201.6 = 7.44% = 7.44/1 = 7.44 moles

Cl = 132.6/201.6 = 65.48% = 65.48/35.5 = 1.84 moles

Divide the number of moles by the smallest"

N = 1.91/1.84 = 1

H = 7.44/1.84 = 4

Cl = 1.84/1.84 = 1

Thus, the empirical formula is NH_4Cl
