How many moles of Sulfur are in 1 mole of Al2(SO4)3
and If the densitry of a noble gas is 1.783 g/L at STP, that gas is....
My guess: Argon?
Then theres a question that says "Which as the greater mole.... and it lists things like:
1 mole Of Ar
1 Mole of O
How would you figure that out?
a. Al2S3O12: three moles S in one mole of aluminum sulfate.
b. 1.783*22.4 g/mole=39.9g/mole>>>Argon
c. I don't know the question being asked. Greater mass? Greater what?
