Total mass of the IBM initials written with 35xenon atomsis approximately 7.63 × 10⁻⁻²¹ grams.The atomic mass of xenon (Xe) is 131.29atomic massunits (amu). To convert this to grams, we need to use theconversion factorbetween atomic mass units and grams, which is 1 amu = 1.6605 × 10⁻²⁴ gm.Therefore, the mass of one xenon atom in grams is:131.29 amu × 1.6605 × 10⁻²⁴ gm/amu = 2.18 × 10⁻²² gmSo, the total mass of 35 xenon atoms in grams is:= 35 × 2.18 × 10⁻²² g= 7.63 × 10⁻⁻²¹gmTo know more aboutxenon atoms, herebrainly.com/question/5516586#SPJ4--The given question is incomplete, the complete question is:"Using scanning tunneling microscopy, scientists at IBM wrote the initials of their company with 35 individual xenon atoms (as shown below).
