Boron trifluoride is used as a catalyst in the synthesis of or-ganic compounds. When this compound is analyzed by massspectrometry several different 1+ ions form, including ions representing the whole molecule as well as molecular fragments formed by the loss of one,two, and three F atoms. Given that boron has two naturally occurring isotopes, ¹⁰B and ¹¹B, and fluorine has one, ¹⁹F, calculate the masses of all possible 1+ ions
