Problem: 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.Assuming that this sample is a statistically representative sample of the element, calculate the percent abundance of each element.

🤓 Based on our data, we think this question is relevant for Professor Czernuszewicz's class at UH.
