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 [tex]O_{2}[/tex]

Explanation:

First you should find the molar mass of the [tex]O_{2}[/tex]:

Molar mass of [tex]O_{2}[/tex] = 2 * molar mass of O

Molar mass of [tex]O_{2}[/tex] = 2 * 16[tex]\frac{g}{mol}[/tex]

Molar mass of [tex]O_{2}[/tex] = 32[tex]\frac{g}{mol}[/tex]

Then you should use the conversion factor:

[tex]30.5molesO_{2}*\frac{32gO_{2}}{1molO_{2}}=976gO_{2}[/tex]

That is in 30.5 moles of [tex]O_{2}[/tex] there are 976g of [tex]O_{2}[/tex]
