The molar ratio of carbon to hydrogen of a volatile liquid compound is 1.2:0.12g of the liquid. On evaporation at STP gave 32cm^3 of vapour.
What is the molecular formula of the liquid?

.
State your process.

You need the mass of the vapour to solve that question.With the mass we can relate it with molar volume to get the molar mass and then get the molecular formular from the empirical formular.

uhmm... So whats the answer?

wow.. so ya'al not able to crack this question? Where are engineers and Lab scientists?

Siiiiiince you know the molar ratio of carbon and hydrogen, you come know the Stp too, how you no come know the molecular formula na? Go and look for it where you kept it.




Peace

na so the question hard?

patiently waiting for the answer

I do know we've got to look for the emperical formular before solving for the molecular formular. . But how do we derive the molar masses from the C and H since they are given in ratios..
