Consider an isomeric mixture of alkenes of molar mass M=70g/mol. Determine the molecular formula of the alkenes.

Hyrogenation of the isomeric mixture produces alkanes. What is the name of the alkane.

If the alkenes in the original mixture are in equimolar proportions what is the mole composition of the alkanes obtained in the above part.

HELP PLEASE THE LAST PART OF THE QUESTION I DIDN'T UNDERSTAND

the molecular formula i think it C5H10
C5H10 is correct for the alkene. The alkane will be C5H12 or pentane, isopentane, or neopentane.
Wouldn't the alkanes be there in equimolar proportions; i.e., the mole fraction would be 0.5.
