The fictiоnаl element Missоuthernium (Ms) hаs three nаturally оccurring isotopes. Isotope A has a mass of 199.79 amu, Isotope B has a mass of 203.45 amu, and Isotope C has a mass of 206.72 amu. If the relative abundance of Isotope A is 42.6%, Isotope B is 35.2%, and Isotope C is 22.2%, what is the average atomic mass of Missouthernium (Ms)?
