The ratio between the molar mass of an alkene(A) and an alkyne(B) with the same number of carbon atoms is 1.05. Find the molecular formulas of the two hydrocarbons then write the reaction for how we can obtain the alkene A from the alkyne B.

We start by remembering the general formulas of alkenes and alkynes:
Alkenes - C_nH_2n
Alkynes - C_nH_2n-2
We calculate the molar mass of both of the...
