The value of n for the given empirical formula and molecular mass is 5.00.

Given the following data:

  • Empirical formula = [tex]C_3H_5[/tex]
  • Molecular mass = 205. 4 g/mol.

Scientific data:

  • Molar mass of carbon (C) = 12 g/mol.
  • Molar mass of hydrogen (H) = 1 g/mol.

To determine the value of n for the given empirical formula and molecular mass:

How to calculate molecular formula.

First of all, we would determine the gram-mass of the chemical compound as follows:

[tex]C_3H_5 = (12 \times 3)+(1 \times 5)[/tex]

C_3H_5 = 36+5

C_3H_5 = 41 g/mol.

For the molecular formula:

(CH)n = 205.4

41n = 205.4

n =\frac{205.4}{41]

n = 5.00
