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.
- Assuming that the sample is statistically representative of a naturally occurring sample, calculate the percent natural
abundance of each Wt isotope. - Draw the mass spectrum for a naturally occurring sample of Wt.
- 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) |
