Verify that the atomic mass of magnesium is 24.31 , given the following information:
\( { }^{24} \mathrm{Mg} \), mass \( =23.985042 \mathrm{u} \); percent abundance \( =78.99 \% \)
\( { }^{25} \mathrm{Mg} \), mass \( =24.985837 \mathrm{u} \); percent abundance \( =10.00 \% \)
\( { }^{26} \mathrm{Mg} \), mass \( =25.982593 \mathrm{u} \); percent abundance \( =11.01 \% \)
(a) The average atomic mass is given as a weighted average of the atomic masses of each isotope. What is the value:
atomic mass \( \times \) fractional abundance
for \( { }^{24} \mathrm{Mg} \) ?
\( \square \)
