Determine the molecular formulas to which the following em-
pirical formulas and molar masses pertain.
a. SNH (188.35 g/mol)
b. NPC1₂ (347.64 g/mol)
c. CoC404 (341.94 g/mol)
d. SN (184.32 g/mol)

Respuesta :

The molecular formula are as follows;

  • S₄N₄H₄
  • N₃P₃Cl₆
  • Co₂C₈O₈
  • S₄N₄

How to find the molecular formulas?

The empirical mass of the compound can be calculated by using the following molar masses(M) .

The molecular formula of the compound can be predicted by finding the number of units of empirical formula:

n = molecular mass / empirical mass

a. SNH (188.35g / mol)

hence,

n = 188.35 / 47 = 4

S₄N₄H₄

b. NPCl₂ (347.64g/mol)

hence,

n = 347.64 / 116 = 3

N₃P₃Cl₆

c. CoC₄O₄ (341.94g/mol)

hence,

n = 341.94 / 170.9 = 2

Co₂C₈O₈

d. SN(184.32g/mol)

hence,

n = 184.32 / 46 = 4

S₄N₄
