Which of the following statements about mass spectrometry is false?
A)Mass spectrometry can be used to determine the molecular weight of a compound.
B)The curvature of the path in a magnetic field is determined by the mass of the ion.
C)The paths of heavier ions are deflected more strongly than the paths of lighter ions.
D)The sample is changed into positively charged ions.

Question

Quizplus · Accepted Answer

The curvature of the path in a magnetic field is actually less for heavier ions compared to lighter ions, because the force experienced by an ion in a magnetic field depends on its charge and velocity, not directly on its mass. Heavier ions, having greater mass, are deflected less than lighter ions for a given charge.
