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 are ^295 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 of ^293 Nv is 293.15 amu and that of 295 Nv is 295.15 amu, what is the atomic weight of Nv? [Section 2.4] | Numerade
