Answer : The mass of sulfur trioxide is, 488.8 grams.

Explanation : Given,

Moles of sulfur trioxide = 6.11 mole

Molar mass of sulfur trioxide = 80 g/mole

Formula used :

[tex]\text{Mass of }SO_3=\text{Moles of }SO_3\times \text{Molar mass of }SO_3[/tex]

Now put all the given values in this formula, we get the mass of sulfur trioxide.

[tex]\text{Mass of }SO_3=6.11mole\times 80g/mole=488.8g[/tex]

Therefore, the mass of sulfur trioxide is, 488.8 grams.
