QUESTION 3 A singly charged ion (an ion that is missing one electron) with a velocity of 3120 m/s is injected perpendicular to a 0.217 T magnetic field, and the ion moves in a circle of 48.6 mm radius. What is the molar mass of the ion in grams? (If you use the standard units, you will get a mass of the ion in kilograms. You must convert that to grams. To get molar mass, you must multiply the mass...
