The following diagram is a representation of 20 atoms of
a fictitious element, which we will call nevadium (Nv).
The red spheres are 293Nv, and the blue spheres are 295Nv.
(a) Assuming that this sample is a statistically representative
sample of the element, calculate the percent abundance
of each element. (b) If the mass of 293Nv is 293.15 amu and
that of 295Nv is 295.15 amu, what is the atomic weight of Nv?
