Question
determining the structure of benzene, an important organic compound, proved to be a difficult challenge for chemists in the 19th century. A sample of benzene was analyzed and found to consist of 1.43 g of carbon and 0.119 g of hydrogen. Given that the molar mass of benzene is 78.0 g, determine both the empirical and molecular formulas for benzene. determining the structure of benzene, an important organic compound, proved to be a difficult challenge for chemists in the 19th century.

moles of carbon =1.43/12
=0.119
moles of H=0.119/1
=0.119
Hence the empirical formula of benzene is CH
the molecular formula be (CH)x.so,
x*(12+1)=78
or x=6
Hence the molecular formula is C6H6
