A compound with an empirical formula of C₂H₄Br has a molar mass of 215.90 g/mol. What is the molecular formula A) C₄H₈Br₂ B) C₂H₄Br C) CHBr D) C₆H₁₂Br₃ E) C₄H₈Br

Question

Quizplus · Accepted Answer

The molar mass of the empirical formula C₂H₄Br is approximately 107.95 g/mol. The molecular formula is a multiple of the empirical formula. 215.90 g/mol divided by 107.95 g/mol is approximately 2, so the molecular formula is C₄H₈Br₂.
