Volume of one atom
The aim of this activity is to calculate the approximate volume of one atom of iron.
will assume that their is no space between each iron atom packed tightly
to form the nail. We will also assume that there are no impurities in
|Place 10 mls of water into a burette as shown on the right.
Record the water level before the nail is placed int he burette. Keep in mind that the scale on the burette is read backwards. The next reading will be lower than the first.
The reading is 44.10
Now record the volume of water after the nail is placed into the burette and submerged.
The reading is 42.40
The difference between the two volumes represents the volume of the iron nail.
The nail has a volume of 1.7 cm3
the volume of one atom of iron
- 1.70 cm3 / 1.38 X 1023 atoms
- 1.23 X 10-23 cm3
the procedure outlined above and measure
the volume of an atom of the following
|What is the radius of an iron atom expressed in nanometres (10-9 m)?
