Chemistry of Mars NASA's 1997 mission to Mars included a small robot, the Sojourner, that analyzed the composition of Martian rocks. Magnesium oxide from a boulder dubbed "Barnacle Bill" was analyzed and found to have the following isotopic composition: Mass (u) Natural Abundance (%) 39.9872 78.70 40.9886 10.13 41.9846 11.17 If essentially all of the oxygen in the Martian MgO sample is oxygen-16 (which has a mass of 15.9948 u), is the average atomic mass of magnesium on Mars the same as on Earth (24.31 u)?
