You are given quantities of aluminum sulfate, #Al_2(SO_4)_3#, and sulfuric acid, #H_2SO_4#. If there are EQUAL numbers of SULFUR atoms with respect to each salt, what is the ratio of oxygen atoms...#Al_2(SO_4)_3:H_2SO_4#?

If the number of sulfur atoms are EQUAL, then the ratio of oxygen atoms, (#Al_2(SO_4)_3:H_2SO_4#) #=# #1:1#

Explanation:

It is given that both salts contain the same number of sulfur atoms. Thus we have #Al_2S_3O_12#, and necessarily #3# #xx# #H_2SO_4#. There are #3# #"equiv"# sulfuric acid per equiv aluminum sufate, and necessarily #"12"# #"equiv"# of #O# atoms in the acid. And (if I have been doing my sums correctly), the ratio of oxygens is #1:1#.

This is a nasty question, which I suspect has been asked below A level.

PS You have just asked a bunch of questions. Do you think that you could spend some time formatting the questions properly? It makes interpreting the question a much easier proposition.
