Answer

5.47 moles of oxygen gas are present in 175 g.

Step-by-step 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

$Mole=\frac{Mass}{Molar\text{ }mass}=\frac{175\text{ }g}{31.998\text{ }g\text{/}mol}=5.47\text{ }mol$

Therefore, 5.47 moles of oxygen gas are present in 175 g.
