Question
A mixture of exactly two moles of helium (He(g)) and one moleof a hydrocarbon of formula CnH2n(g) is placed in a container witha small hole through which the gas can escape. The escaping gas iscollected and was found to have 6.48 times more Helium than thehydrocarbon. What is the molar mass of the hydrocarbon? Whatis the formula of the hydrocarbon (what is the value of"n")?
