Question

The empirical formula of a compound is ch. it's molar mass is 52.07 g/mole. What is its molecular formula?

Answer 1

To determine the molecular formula we do as follows:

let x number of C
therefore number of H is x as well

x (12.01) + x (1.01) = 52.07
x = 3.999 = 4

Therefore, the molecular formula would be C4H4. Hope this helps.
