Link to Periodic Table of the Elements
o Only C10H1202
Neither C5H.0 nor C10H 1202
Only CsHO
Either C5H.0 or C10H1202

Answer 1

Answer: Either
`C_5H_6O` or
`C_(10)H_(12)O_2`

Step-by-step explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.

The empirical formula is
`C_5H_6O`

Now we have to calculate the molecular formula:

`n=\frac{\text{Molecular weight }}{\text{Equivalent weight}}`

n is a whole number

The molecular formula could be=
`1* C_5H_6O=C_5H_6O`

Thus molecular formula could be =
`2* C_5H_6O=C_(10)H_(12)O_2`
