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

Butterfly wingspan is 7.7

You use the atomic number to find out how many protons and neutrons there are in the atom. you use the atomic mass to find out how many protons and electrons there are in the atom.
