Find the molecular formula for a compound with an emperical formula C2H2N and a molar mass of 46g/mol

Answer 1

The molecular formula is a whole number multiple of the empirical formula.

The molar mass of the empirical formula C₂H₂N = 24 + 2 + 14 = 40

If you meant to write that the molar mass was 40 g /mol, then the molecular formula would be C₂H₂N.

If you actually meant that the molar mass was 46 g /mol, then there is no such compound.

So, please check the question again, and make sure you copied it correctly.
