From it's Molecular mass, you would get the molecular structure...not in al aspects though, but it's shorter here....C=carbon----»12, H=hydrogen----»1...check for the option that give 26 as its Molar mass in the Options given..you would realise option A has got 2moles of C and 2moles of H, now multiply its moles by Its Molar Mass and add Up...C2H2=(12 x 2) + (1 x 2)=26

A is correct, C2H2 ===>Ethyne

How did you get Carbon to be 12. I thought molar mass of carbon is 16

92.3/12=7.7 and not 7.1 tnx
