The mass of an ion can be determined by measuring its cyclotron frequency in a strong magnetic field. The cyclotron frequency of ion X+ (with charge q=1.6×10−19Cq=1.6×10-19C is measured to be 2.3 MHz in a 1.8 T magnetic field. What is the mass of ion X+ in atomic mass units? Note: one atomic mass unit is 1 amu = 1.66×10-27 kg.)
