Question 10

An extraterrestrial mineral sample recovered from a carbonaceous chondrite meteorite contains a non-standard isotopic distribution of boron. Mass spectrometry analysis reveals that the boron in this sample consists of 18.43% boron-10 and 81.57% boron-11.

Calculate the relative atomic mass ( $A_r$ ) of boron in this meteorite sample. Give your answer to two decimal places. You must show your working.
