When an element shares electrons with other atoms of the same or different elements to acquire stable electronic configuration, it is called covalency. If an atom shares 1 electron, its covalency is equal to 1. ... It needs 3 electrons to complete its octet.

1.31 × 10⁴ grams.
<h3>Explanation</h3>
Assume that oxygen acts like an ideal gas. In other words, assume that the oxygen here satisfies the ideal gas law:
,
where
the pressure on the gas, 
;
the volume of the gas, 
;
the number of moles of the gas, which needs to be found;
the absolute temperature of the gas, 
.
the ideal gas constant, 
if P, V, and T are in their corresponding SI units: Pa, m³, and K.
Apply the ideal gas law to find :
.
In other words, there are 410.3 moles of O₂ molecules in that container.
There are two oxygen atoms in each O₂ molecules. The mass of mole of O₂ molecules will be 
. The mass of 410.3 moles of O₂ will be:
.
What would be the mass of oxygen in the container if the pressure is approximately the same as STP at 
or 
instead?
Answer:
The reason is because Charle's Law which states that volume is directly proportional to temperature. So, for the temperature to be absolute zero, there would need to be no volume. It's Impossible.
