9. A new element, Albanesium, has been discovered. 43.2% of all naturally occurring Albanesium has a mass of 292 amu. 46.8% of all Albanesium has a mass of 293 amu. The rest
of the Albanesium has a mass of 295 amu. Find the average atomic mass of Albanesium.

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.
