There are four isotopes of strontium. They have mass number of 84, 86,87 and 33. The atomic mass of strontium is 87.62 amu. What does it say about the relative abundance of isotopes?
Gallium is a metal which forms compounds with a wide variety of uses. Some of the applications of gallium compounds include computer memory chips, light emitting diodes and lasers. Radioactive isotopes of gallium are used to image the human body and locate tumors. Naturally occurring gallium consists of two isotopes. One of those isotopes is 71Ga with an isotopic mass of 70.9247050 amu and an abundance of 39.892%. What is the mass number of the other isotope?

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 100 Ru 99.90 58.% 96 Ru 95.91 42.% 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.
