How heavy would 24000 cm3 of that be?

So 1.33x10^-3 x24000 which is 32 is oxygen as o2 has a mass of 32

Aha, but sulfur is also 32. Why not sulfur?

At room temp and pressure so in standard states? So sulfate in its standard state would be S2 so the mass would be 64

Sulfur has a number of allotropes, S8 is probably the most common. S2 pretty much doesn't exist at 298 K.

Whichever allotrope you consider, they're all heavier than 32 and most of them are solid anyway.
