We’re being asked to calculate the atomic mass of magnesium. We can use the following equation:
where atomic mass = average atomic mass of the element and f.a. = fractional abundance of the isotope. To get f.a., we simply need to divide the given percent abundance by 100.
Magnesium has three naturally occurring isotopes with masses of 23.99 amu, 24.99 amu, and 25.98 amu and natural abundances of 78.99 %, 10.00 %, and 11.01 %, respectively. Calculate the atomic mass of magnesium.
