The following diagram is a representation of 20 atoms of a fictitious element, which we will call nevadium (Nv) The red spheres are 293 Nv, and the blue spheres are295 Nv.
(a) Assuming that this sample is a statistically representative sample of the element, calculate the percent abundance of each element .
(b) If the mass of293 Nv is 293.15 amu and that of 295 Nv is 295.15 amu, what is the atomic weight of Nv? [Section 2.4]
