Product Description
Purpose:
1) Determine the average weights of each isotope of the fictitious element Vegium.
2) Determine the percent abundances of the isotopes of vegium
3) Calculate from experimental data the atomic mass of vegium

In this lab you will carry out experiments and perform the necessary calculations to determine the atomic mass of the fictitious element vegium. The three different isotopes of vegium are beanium, peaium, and cornium. Your job will be to obtain a sample of vegium and determine the relative abundance of each isotope and the mass of each type of particle. From this data you will calculate the weighted average mass, or atomic mass, or vegium.

Materials needed: Electronic Balance, Sample of vegium (plastic cup with assorted corn, bean, and pea seeds), Calculator
