C because, its products is heavier than each of its reactants
The molecular formula of the compound which has a molecular weight of 112.124 atomic mass units is C₆H₈O₂.
<h3>What is molecular formula?</h3>
Molecular formula of any compound tells about the composition and numbers of each entities present in that molecule.
Steps involved in the prediction of molecular formula:
- First we predict the molar mass of given emperical formula as:
Molar mass of C₃H₄O = 3(12) + 4(1) + 16 = 56
- Now we divide the given mass by the calculated mass of empirical formula:
112.124/56 = 2
- Now we multiply the subscripts of given empirical formula by this whole number and we get:
Molecular formula = (C₃H₄O)₂ = C₆H₈O₂
Hence correct option is (E).

In the winter bears hibernate because food is scarce during the winter, and it is also very cold. During hibernation a bears body temperature drops, and they do not go to the bathroom. This helps them preserve energy as they sleep throughout the winter. Which is what keeps them alive. Hope I could help!!:-)))
