Description : How many sulfur atoms are present in 25.6 g of Al2(S2O3)3?
Last Answer : First of all, your formula cannot be right. There is no way the formula is Al2S2O33. Sorry, not happening. Maybe it is supposed to be Al2S2O3? But you need to know the actual formula to answer this ... . To do that multiply by Avogadro's number and see the Related Questions links for how to do that!
