In 2006, a russian team discovered an interesting molecule they called "sulflower" because of its shape and because it was based on sulfur. it is composed of 57.17% s and 42.83% c and has a molar mass of 448.70 g/mol. determine the empirical and molecular formulas of "sulflower."

The empirical and molecular formula for the given organic compound is and   respectively.

Explanation:

We are given:

Percentage of C = 42.83 %

Percentage of S = 57.17 %

Let the mass of compound be 100 g. So, percentages given are taken as mass.

Mass of C = 42.83 g

Mass of S = 57.17 g

To formulate the empirical formula, we need to follow some steps:

Moles of Carbon =

Moles of Sulfur =

For the mole ratio, we divide each value of the moles by the smallest number of moles calculated which is 1.79 moles.

For Carbon =

For Sulfur =

The ratio of C : S = 2 : 1

Hence, the empirical formula for the given compound is

For determining the molecular formula, we need to determine the valency which is multiplied by each element to get the molecular formula.

The equation used to calculate the valency is:

We are given:

Mass of molecular formula = 448.70 g/mol

Mass of empirical formula = 56 g/mol

Putting values in above equation, we get:

Multiplying this valency by the subscript of every element of empirical formula, we get:

Thus, the empirical and molecular formula for the given compound is and
