Answer: The number of moles of [tex]O_2[/tex] are 6.

Explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number [tex]6.023\times 10^{23}[/tex] of particles.

To calculate the moles, we use the equation:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text {Molar mass}}[/tex]

Given mass = 192 g

Molar mass = 32 g/mol

[tex]\text{Number of moles}=\frac{192g}{32g/mol}=6mol[/tex]

The number of moles of [tex]O_2[/tex] are 6.
