Matter and Measurement

In the universe, there is matter, energy, and void space. The universe contains energy and void space. The definition of matter can be considered as something which possesses mass and consumes space. Chemistry is that branch of science which deals with the study of matter. Under chemistry, nature, composition, and the changes occurring to matter are discussed.

A robot spacecraft returned samples from the planetesimal 98765 ALEKS, located in the outer Solar System. Mass-spectroscopic analysis produced the following
data on the isotopes of ruthenium in these samples:
mass relative
isotope (amu) abundance.
96 Ru 95.91 51.%
99 Ru 98.91
49.%
Use these measurements to complete the entry for ruthenium in the Periodic Table that would be used on 98765 ALEKS. Round your entry for the atomic mass
to 2 significant digits.
Caution: your correct answer will have the same format but not necessarily the same numbers as the entry for ruthenium in the Periodic Table we use here on
Earth.
