Question

Determine the molecular formula of the compound with an empirical formula of CH and a molar mass of 65.09 g/mol.

Answer 1

Answer:

empirical formula mass=12+1=13 g/mol

n=molecular mass /empirical formula mass

n=65.09/13=5.006=5 (rounding off)

molecular formula =n(empirical formula)

=5(CH)=C5H5
