what is mass spectrometry primarily used for? measuring the speed of light measuring the temperature of gases measuring the mass - to - charge ratio of molecules measuring the volume of liquids
Answer
Brief Explanations:
Mass spectrometry ionizes chemical species and sorts the ions based on their mass - to - charge ratio. It is not used for measuring light speed, gas temperature, or liquid volume.
Answer:
C. Measuring the mass - to - charge ratio of molecules
