WebAn ion with a mass of 100 u (unified atomic mass units) ( m = 100) carrying two charges ( z = 2) will be observed at m/z = 50. However, the empirical observation m/z = 50 is one equation with two unknowns and could have arisen from other ions, such as an ion of mass 50 u carrying one charge. WebYou can find the mass M by the formula m/z = (M + nxprotons)/n where n is the charge.
