If a random sample of this element collected from the tail, Ask an Expert

Academics

Boron has two principal naturally occurring isotopes, 10B (isotopic mass 10.013 amu) and 11B (isotopic mass 11.009 amu). If a random sample of this element collected from the tail of a comet has an weighted average atomic mass of 10.788 amu, what is the percent abundance of the lower-mass isotope?
