Question

What is the molecular formula of a molecule that has a molecular mass of 180.8 g/mol and an empirical formula of CH2O?

Answer 1

Answer:

The compound is  "C6H12O6"

Explanation:

we know the relation that

Molecular formula mass = n. (Empirical formula mass)

180.8=n(30.0156)

n= 6

So

Molecular formula = n. (Empirical formula)

Molecular formula= 6 ( CH2O)

Molecular formula = C6H12O6
