Explanation

To find the mass (m) of an ion of , the weight in atomic mass unit (amu) will have to be converted to kilograms (kg). The carbon ion ( ) is represented as which indicates that the atomic mass of the this carbon ion is 12 amu. By definition, one amu is one-twelfth (1/12th) of the mass of a Carbon-12 atom ( ). Moreover, one Carbon-12 atom has a mass of approximately grams, since there are atoms (which equals Avogadro's number ) in one mole. This gives us grams. We also need to convert from grams to kilograms as the standard metric unit for mass is kg as norated in the international system (SI) of units. To convert, we need to know that 1 gram is Kg.
