Ok I just want to see how many of you guys get the questions right (no google please) :

1)- According to the Hubble space telescope, the known universe is expanding. What is it expanding in to and how far can it expand?
2)- How many atoms are in these elements:
CaSO4

4NaOCl

Fe(NO3)2

2Al2(CO3)3
Can I just add I noticed that those are actually compounds (or elements) more answers please!
 
1) It isn't expanding _into_ anything. It is the space within the Universe that is expanding rather than the Universe that is expanding within some larger containing medium.

2) None of those are elements.
