Given the empirical formula of your compound is CH₂, what is the gram formula mass of the empirical formula?

14g

Explanation:

The empirical formula of the compound is CH₂ ;

When we are dealing with compounds the gram formula mass or gram - molecular weight is the molar mass of the compound.

It is determined by adding the atomic masses of the components together and then expressed in grams.

 Atomic mass of C  = 12

 Atomic mass of H  = 1

  Gram formula mass = 12 + 2(1)  = 14g
