A mixture of benzene, toluene, and methane was injected into a gas chromatograph. Methane gave a sharp spike in 42 seconds, whereas benzene required 251 seconds and toluene eluted in 333 seconds. Ethylbenzene was eluted at 350 seconds. Find its retention factor and the relative retention and unadjusted relative retention time for ethylbenzene and toluene.
