What would be some of the properties of oxygen,if it were turned into a liquid? ?

Liquid oxygen (also called Lox) has a pale blue color and is strongly paramagnetic: it can be suspended between the poles of a powerful horseshoe magnet. Liquid oxygen has a density of 1.141 g/cm3 and is cryogenic with a freezing point of 54.36 K and a boiling point of 90.19 K at 101.325 kPa. Liquid oxygen has an expansion ratio of 1:861 under 1 standard atmosphere  and 20 °C (68 °F). Because of this, it is used in some commercial and military aircraft as transportable source of breathing oxygen.

Answer;

= 3.064 g/L

Explanation;

Using the equation;

PV = nRT , where P is the pressure,. V is the volume, n is the number of moles and T is the temperature and R is the gas constant, 0.08206 L. atm. mol−1.

Number of moles is 1 since one mole has a mass equivalent to the molar mass.

Therefore; We can find the volume and thus get the density.

V = nRT/P

   = (1 × 0.08206 × 498 )/ 0.939

   = 43.52 L

But; density = mass/volume

Therefore;

Density = 133.34 / 43.52

             = 3.064 g/L
