How to convert each quantity into Moles of Sulfur??? HELP!!!?

I must round off correctly and ahow calculation setup. I did a few on my own, but these are a little complicated for me.

Any help would be appreciated.

1.) 2 moles of SnS2?

2.) 3.01 times 10 to the 23rd power molecules of H2S?

3.) How many grams of O in 2.10 moles of H3PO4(aq)?

4.) How many moles of H in 1.20 moles of H3PO4(aq)?

5.) How many moles is 49.00 grams of H3PO4(aq)? How

many molecules is that?

6.) Okay, for this one, I did the first part of it which is:

Convert 5.40 grams of boron to moles? The answer I got

was 0.500 mol of B(Boron) right?

Now the next part says:

How many atoms of boron is that? So, I multiply 6.02

times 0.500 mol B and the answer I got was 3.10 times

ten to the 23rd power?
