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?

  • Chemistry -

    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?
