What is the average atomic mass of the element with the isotopic abundances shown Use the correct number of significant figures in your answer. Do not use scientific notation.?

To calculate the average Atomic Mass of an element based on isotopic abundances, you multiply the mass of each isotope by its relative abundance (expressed as a decimal), then sum these values. Finally, round the result to the appropriate number of significant figures based on the data provided. Without specific isotopic masses and abundances, I can't provide a numerical answer, but the procedure remains the same.
