What are the empirical formula and empirical formula mass for N2S3

Answers

Answer: 1)empirical formula

=> a formula giving the proportions of the elements present in a compound but not the actual numbers or arrangement of atoms.

Element Symbol Entered Percent Actual Percent Moles

Nitrogen N 22.53% 22.55% 2

Sulphur s 77.47% 77.45% 3

Explanation:

The empirical formula of a compound is derived from the number of moles of the constituent elements of the compound. The empirical formula of dinitrogentrisulphide is N₂S₃ itself. It formula mass is 124 g.

What is empirical formula ?

The empirical formula of a compound is derived from the number of moles of the constituent elements present in the compound. The number of moles can be determined from the mass percentage if given for each element.

The empirical formula mass is the mass from the number of atoms and atomic masses of elements from the empirical formula

Here, the empirical formula of the given compound is N₂S₃ itself.

Atomic mass of N = 14 g/mol

mass of two nitrogens = 28 g

Atomic mass of sulphur = 32 g/mol

mass of 3 sulphur = 3 × 32 = 96 g

then formula mass of N₂S₃ = 96 g +28 g = 124 g/mol

Therefore, the empirical formula mass of the compound N₂S₃ is 124 g/mol. Where, nitrogen is present in 22.5% and sulphur is present in 77.4%.
