Answer : The mass of oxygen is 160 grams.

Solution : Given,

Moles of
O_2 = 5 moles

Molar mass of
O_2 = 32 g/mole

Formula used :


\text{ Mass of }O_2=\text{ Moles of }O_2* \text{ Molar mass of }O_2


\text{ Mass of }O_2=(5moles)* (32g/mole)


\text{ Mass of }O_2=160g

Therefore, 160 grams of
O_2 are in 5.0 moles of the oxygen gas.
