Question

styrene has empirical formula CH and there is 92.2%C and 7.75%H if molar mass is 104. what will be integral multiple(n) to get molecular formula? ​

Answer 1

Answer:

Given what I have said:

(Empirical formula)×n=Molecular formula

(CH)×n=104⋅g⋅mol−1

(12.01+1.01)⋅g⋅mol^−1×n=104⋅g mol^-1

Clearly,

n=8, and the molecular formula is C8H8 .

Of course this is reasonable inasmuch that we know that the styrene monomer is

C6H5CH=CH2 , i.e. vinyl benzene.

Answer 2

Answer:

eight integral multiple to get molecular formla
