guys how do i do this question???

1)SO2(G) + CaSO3(aq)-->CaSO3(aq) + H2O(l)

what mass of calcium hydroxide would be needed to deal with 1000dm^3 of sulphur dioxide?
( I got 1,155.96g but thts seems wrong)
also

2) What mass of Iron(3)oxide would need to be reduced to produce 100tones of iron ina blast furnace (I got 71.5tonnes but i think thts wrong)

Dear ChuckDichromate;

You are right! ,  -  There are not only both results wrong!
Also the RxN of question 1.) is wrong.

Both are normal "Stoichiometry Problems":
So you may apply the recipe/scheme from the Topic "Stoichiometry Problem":   "Stoichiometry Problem (#23'025)"
Therein is also an Example Diagram: How to do a "Stoichiometry Problem".

Additional Hint: 
    -   How many moles SO₂ are 1000 dm³ (= 1000 L) at STP?
    -   Are more or less than 100t of Fe₂O₃ required to build 100t Fe?

Good Luck!
