The equation for the reaction between hydrogen gas and oxygen gas is:

2H2(g) + O2(g) ---> 2H2O(l)

i) How much hydrogen will react with 8g of oxygen?

ii) how much water will be formed when 6g of hydrogen react?

i would appreciate your help.

Both i) and ii) are simple stoichiometry problems (as opposed to limiting reagent problems).I have posted an example problem of this type. Just follow the steps.
