Your forensic chemistry group, working closely with locallawenforcement agencies, has acquired a mass spectrometer similartothat discussed in the text. It employs a uniform magneticfieldthat has a magnitude of 0.80 T. Tocalibrate the massspectrometer, you decide to measure the massesof various carbonisotopes by measuring the position of impact ofthe various singlyionized carbon ions that have entered thespectrometer with akinetic energy of 22keV. A wire chamber with position sensitivityof 0.45 mm is part of the apparatus. What will be thelimit on itsmass resolution (in kg) for ions in this mass range,that is, thosewhose mass is on the order of that of a carbonatom?
1 kg
