Question

A mass spectrometer is being used to separate common oxyg these oxygen isotopes is related to climatic time the ice oxygen-16 is 2.66 x 103 kg, and t when they hit a target after traversing a semicirde? hey are singly charged and travel at s.30 x 101 m/s in a 1.90 T magnetic field. What is the separation (in m) between thesr paths ature at the time the ice was deposited.) The ratio of the masses of these two ions is 16 to 18, the mass of arer oxygen-18, taken from a sample of old glacial ice. (The relative abundance of

Explanation / Answer

m16 = 2.66*10^-26 kg
m18 = (18/16)*2.66*10^-26 kg
= 2.99*10^-26 kg

r = mv/qB

d = 2(m18-m16)v/qB
= (2(2.99*10^-26-2.66*10^-26)*(5.30*10^6))/(1.6*10^-19*1.90)
= 0.115 m
