Title: Bean Bag Isotopes (frequency and relative atomic mass)

Objective: The purpose of this experiment is to the properties of mass and relative abundance of isotopes of the element study "bean bag" (symbol, BG) and the atomic weight of this element to be calculated. "

Procedure:
1. "Sort of atoms in the bag" bean "element in the sample (BG) in three groups of isotopes (1,2 and 3) the type of grain. (It is assumed that each kind of grain, the manifold and an isotope grains are separated one atom.) Put each group of isotopes in a separate bowl weighing or small cup. "

2. "Count and record the number of atoms in each BG Group isotopes."

3. "The measurement of the total mass of the atoms BG belonging to different groups of isotopes. Records of all the mass to an accuracy of 0.01 g in the table. Note: zero (tare) and the overall record with an unladen weight of the plate and the mass. Do this for each group. "

Dates:
"Bean Bag" of isotopes - atomic number - the total mass of the atoms
1. Red144 39.9 g
2. Black 40 7.67 g
3. White 10 2.56 g

Results:
"Bean Bag" of isotopes - Mass Media - Percentage abundance
1. About Red Hat: 2777 More: 74.2%
2. Black About: About 19.175: 20.62%
3. About Blanco, about 256: 5.15%

Conclusion:
