Tina and flycd05, i have another question to ask you:
in stochiometry problems, when we are ask to see which is the limiting rxn and we are given lets say 100 grams of H and 100 grams of O2, and we want to find the # of moles that is in 100g, do we divide 100 by 2 go get the number of moles of H or by 1 also, for O2 do we divide by 16g or 32g?
i always mix this up! thanks.
