What is the molecular formula of the compound ch2 with molar mass =168g/mol?

The molecular formula to the given empirical formula is

Explanation:

Empirical formula is defined as the simplest form of the chemical formula that represents the whole number of atoms of each element that are present in the compound.  Here, the empirical formula is

Molecular formula is defined as the chemical formula that represents the actual number of atoms of each element that are present in the compound.  

To determine the molecular formula, we first need to determine the valency which is then multiplied by each element to get the molecular formula.

The equation which is used to calculate the valency follows:

Empirical mass =

Molecular mass = 168 g/mol

Putting values in above equation, we get:

Now, multiplying this number to the subscripts of atoms of , it gives:

Hence, the molecular formula to the given empirical formula is

i think it's c. i'm not sure but i think so.
