Answer
5.47 moles of oxygen gas are present in 175 g.
Explanation
The number of moles of oxygen gas present in 175 g can be known by dividing the mass of the oxygen gas by its molar mass.
The molar mass of O₂ = 31.998 g/mol
[tex]Mole=\frac{Mass}{Molar\text{ }mass}=\frac{175\text{ }g}{31.998\text{ }g\text{/}mol}=5.47\text{ }mol[/tex]Therefore, 5.47 moles of oxygen gas are present in 175 g.
