The original mixture contains petroleum ether, 1-hexene,
and 1-bromohexane in a 1:1:1 ratio.
Petroleum ether has the lowest boiling point range of
40-60ºC and the lower boiling point compounds travel through the
column faster than the higher boiling point compounds. 1-hexene
would have the second highest retention time with its boiling point
of 63ºC and 1-bromohexane would have the lowest with a boiling
point of 143ºC.

Most elements occur naturally as a mix of different isotopes. An element's atomic mass is the weighted average of the isotope masses. In other words, it is an average that takes into account the percentage of each isotope. For example, the two naturally occurring isotopes of boron are given here The atomic mass of boron is calculated as follows: (10.0 times 0.199) + (11.0 times 0.801) = 10.8 amu Because the heavier isotope is more abundant the atomic mass a...
