Answer:
The molecular formula is C2H2Br4
Explanation:
Molar Mass of CHBr2 = 12 + 1 + (2x80) = 12 + 1 + 160 = 173
The molecular formula = n x empirical formula
Molar Mass of the compound = 345.6
Empirical formula = CHBr2
n(CHBr2) = 345.6
n x 173 = 345.6
n = 345.6/173 = 2
Therefore the molecular formula is n(CHBr2) = 2(CHBr2) = C2H2Br4
