I am COMPLETELY LOST for this one...dnt even know where to start

MOLES

1) Lithium Hydroxide reacts with Carbon Dioxide to form solid Lithium Carbonate and Water. How many grams of carbon dioxide can be absorbed by each 1 gram of lithium hydroxide.

2) Part of the SO2 (sulfur dioxide) that is introduced into the atmosphere by combustion of sulfur containing compounds ends up being converted to sulfuric acid.
I wrote the formula

2SO2 (g) + O2 (g) ----> 2H2SO4 (aq)

How much sulfuric acid can be formed from 5 moles of SO2 (sulfur dioxide), 2 moles of O2 (oxygen) and an unlimited quantity of water?

One question to a post please.
For 1. This is a plain and simple stoichiometric problem.
Write the equation and balance it.
2LiOH + CO2 ==> Li2CO3 + H2O

Convert 1 g LiOH to mols.
Use the equation coefficients to convert mols of LiOH to mols CO2.
Convert mols CO2 to grams CO2.
Will post #2 later.

#2.
I will argue that your equation is not quite correct although using it will give you the correct answer.
2SO2 + O2 ==> 2SO3
SO3 + H2O ==> H2SO4

Probably you will not need help with this one after you finish the LiOH problem above. But if you do, post your thinking and we can help you through it.
