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 :
\(\text{ Mass of }O_2=\text{ Moles of }O_2\times \text{ Molar mass of }O_2\)
\(\text{ Mass of }O_2=(5moles)\times (32g/mole)\)
\(\text{ Mass of }O_2=160g\)
Therefore, 160 grams of \(O_2\) are in 5.0 moles of the oxygen gas.
