if you had 120 grams of sugar and all of it decomposed,how many moles of water were decomposed?
Your question makes no sense. Perhaps you want to know how many moles H2O were formed. That would be 120/molar mass sugar = moles sugar.
moles H2O formed = 11 x moles sugar.
Its been a while since CHem but since this is homework help and not HW do lets start by asking you, what is the formula for sugar? And while your at that write in your own words what a mole is, so I know your level of comprehension and can go into that if desired.
