the answer is c a chemical equation
<span>The astronaut then measures the abundance of magnesium on the new planet, obtaining the following results:
Isotope Abundance (%) Mass (amu)
24Mg 78.99 23.99
25Mg 10.00 24.99
26Mg 11.01 25.98
The atomic mass of magnesium for this planet = </span><span>24.31 amu</span>
