|the table below gives the atomic mass and relative abundance values for the three isotopes of elemerelative abundance (%)78.9910.00(11.01atomic mass (amu)23.9850124.985825.9826what is the average atomic mass (in amu) of element m? o2.865.3624.3024.98mark this and return

To calculate the average atomic weight, each exact atomic weight is multiplied by its percent abundance, then add the results together and round off to an appropriate number of significant figures. So according to what’s given, the average atomic mass of elements M should be (23.9850 x 0.7899) + (24.9858 x 0.1000) + (25.9826 x 0.1101) = 24.30

Ithink it’s 3 as the answer.
