Glucose is a carbohydrate that contains carbon, hydrogen, and oxygen. the empirical formula of glucose is ch2o and its molar mass is 180.12 g/mol. find the molecular formula of glucose.

The molecular formula of glucose is

Explanation:

We are given:

Empirical formula of the compound =

Empirical mass of the compound =

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 = 180.12 g/mol

Mass of empirical formula = 30 g/mol

Putting values in above equation, we get:

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

Hence, the molecular formula of glucose is

i'm pretty sure its b i might be wrong though!
