The answer is 0.5 moles because if 1 moles of o2 is consumed to produce 2 moles of Na2O, then 0.5 moles of o2 will be consumed to produce 1 mole of Na2O.

Answer : 0.5 moles of oxygen are completely consumed in the production of 1.00 mole of [tex]Na_2O[/tex]

Solution : Given,

Moles of [tex]Na_2O[/tex] = 1 mole

The given balanced reaction is,

[tex]4Na+O_2\rightarrow 2Na_2O[/tex]

From this balanced reaction, we conclude that

As, 2 moles of [tex]Na_2O[/tex] produces from 1 moles of [tex]O_2[/tex]

So, 1 mole of [tex]Na_2O[/tex] produces from [tex]\frac{1}{2}=0.5[/tex] moles of [tex]O_2[/tex]

Therefore, 0.5 moles of oxygen are completely consumed in the production of 1.00 mole of [tex]Na_2O[/tex]
