Crystal Structures

Solids are present all around us. They have different properties and applications. Diamond and graphite are two well-known solids. Diamond is the hardest material in the world and is used in making jewelry. Graphite on the other hand is soft. The lead of your pencil is graphite. Why are they so different in appearance and properties despite the fact they are chemically the same? Both are allotropes of carbon. The answer lies in the structure, the way constituent particles are arranged in the solids.

The noble gas argon was discovered by Sir Walter Ramsay and John William Strutt in England in 1895. Through this discovery, they made highly accurate measurements of gas densities. Their experimentally determined densities are: Oxygen 1.42952 g/L Nitrogen 1.25718 g/L Air 1.29327 g/L 1) To determine the density of atmospheric nitrogen, Strutt removed the oxygen, water, carbon dioxide, and argon from air and then filled an evacuated glass tube with the remaining gas. He determined that a mass of 0.20389 g of nitrogen has a density of 1.25718 g/L under standard conditions of temperature and pressure. What is the volume of the glass tube in cm3?
