Magnesium has three stable isotopes. The most commonly occurring isotope, $^{24}Mg$, has an isotopic mass of 23.985 u and makes up 78.99% of naturally occurring magnesium atoms. The isotope $^{25}Mg$ makes up 10.00% of magnesium atoms and has an isotopic mass of 24.986 u. The isotope $^{26}Mg$ makes up 11.01% of magnesium atoms and has an isotopic mass of 25.983 u. Using the isotopic composition provided, calculate the average atomic mass of magnesium. average atomic mass: u
