Chemistry question regarding calculating masses of isotopes?
Magnesium has three naturally occurring isotopes. 24Mg (23.985 amu) with 78.99% abundance, 25Mg (24.986 amu) with 10.00% abundance, and a third with 11.01% abundance. Look up the atomic mass of magnesium, and then calculate the mass of the third isotope.
