#### Work Step by Step

Average atomic mass = $0.0800*45.95232+0.0730*46.951764+0.7380*47.947947+0.0550*48.947841+0.0540*49.944792=47.9$ amu Referring to the Periodic Table, we see that Titanium has an average atomic mass of 47.867 amu which most closely matches Element X's average atomic mass of 47.9 amu. Therefore Element "X" is most likely Titanium.
