Physical Properties of oxygen
- In its normal state, the gas is tasteless, odorless, and insipid. It has a small paramagnetic field. With the exception of helium, neon, krypton, and argon, it reacts with every element and produces oxides with them. It dissolves somewhat in water.
- One of the frequently seen forms of oxygen is dioxygen.
- The most reactive oxygen allotrope that could harm lung tissue is trioxygen. The name of this allotrope is ozone.
Determining the weight of an oxygen molecule
Mass of one oxygen atom = 16g
- Mass of 1 mole of O2 molecule = 2 x 16 = 32g
- Number of molecules in 1 mole = 6.022 x 1023
- Mass of 1 molecule of O2 is = 32/ 6.022 x 1023 = 5.32 x 10-23 g
Hence, the mass of 1 molecule of O2 is 5.32 x 10-23 g
Calculate the mass of the O2 molecule.
The mass of the O2 molecule is 5.32 x 10-23 g. Oxygen is used in the production and manufacturing of glass and stone products, and in mining.
