Unknown on these data....

Explanation:

We got an empirical formula of #CH#...

We further know that the molecular formula is a whole number multiple of the empirical formula...i.e.

#"molecular formula"=nxx"empirical formula"#

And thus to access the molecular formula, we need an estimate of molecular mass. We ain't got this...we were only quoted the MASS of the sample...
