Chapter 1, Problem 88E

To the right is a representation of 50 atoms of a fictitious element called westmontium (Wt). The red spheres represent Wt-296, the blue spheres Wt-297, and the green spheres Wt-298.

1. Assuming that the sample is statistically representative of a naturally occurring sample, calculate the percent natural abundance of each Wt isotope.
2. Draw the mass spectrum for a naturally occurring sample of Wt.
3. The mass of each Wt isotope is measured relative to C-12 and tabulated here. Use the mass of C-12 to convert each of the masses to amu and calculate the atomic mass of Wt.

Isotope	Mass
Wt-296	24.6630 x Mass(12C)
Wt-297	24.7490 x Mass(12C)
Wt-298	24.8312 x Mass(12C)
