A sample containing carbon, oxygen, and an unknown element isplaced in a mass spectrometer. The ions all have the samecharge and are accelerated through the same potential differencebefore entering the magnetic field. The carbon and oxygenlines are separated by 2.250 cm on the photographic plate, and theunknown element makes a line between them that is 1.160 cm from thecarbon line.
a) What is the mass of the unknown element?
b) Identify the element.
