Molar mass O₂ = 16 x 2 = 32.0 g/mol

1 mol O₂--------------------------- 32.0 g
30.5 moles O₂-------------------- ? ( mass O₂)

mass O₂ = ( 30.5 ) x 32.0 / 1

mass O₂ = 976.0 / 1

= 976.0 grams of O₂

hope this helps!

Answer:

976g of \(O_{2}\)

Explanation:

First you should find the molar mass of the \(O_{2}\):

Molar mass of \(O_{2}\) = 2 molar mass of O

Molar mass of \(O_{2}\) = 2 16\(\frac{g}{mol}\)

Molar mass of \(O_{2}\) = 32\(\frac{g}{mol}\)

Then you should use the conversion factor:

\(30.5molesO_{2}*\frac{32gO_{2}}{1molO_{2}}=976gO_{2}\)

That is in 30.5 moles of \(O_{2}\) there are 976g of \(O_{2}\)
