A new element, Mm, has been discovered with an atomic number of 30. Mm has three naturally occurring isotopes and is an essential element in the human diet. The research team's goal is to determine the average atomic mass of Mm by finding the percent abundance of each isotope and calculating the mass contribution of each one. They have already determined the masses of the three Mm isotopes and now need to perform calculations to find the percent abundances and average atomic mass.

2. New Discovery!!! You and your research team have discovered a new element…Mm… Mm is an essential element in the human diet There are three naturally occurring isotopes of the element Mm Atomic Number of Mm is 30 Your teams goal is to determine the average atomic mass of the element Mm by determining the percent abundance of each naturally occurring Mm isotope You have already determined the masses of each of the three different Mm isotopes:

3. Calculations Percent Abundance of isotope Mm-R= (Total # of Mm-R in nature/ Total # of all Mm-isotopes in nature) x 100% Percent Abundance of isotope Mm-B= (Total # of Mm-B in nature/ Total # of all Mm-isotopes in nature) x 100% Percent Abundance of isotope Mm-Y= (Total # of Mm-Y in nature/ Total # of all Mm-isotopes in nature) x 100% Mass Contribution of each isotope: (amu of Mm isotope) x (percent abundance of Mm isotope in nature) Average Atomic Mass= [(mass contribution of Mm-R) + (mass contr. of Mm-B) + (mass contr. of Mm-Y)] Show ALL Calculations Take Pictures of Set up Record all procedures
