Answer:

In one mole of stuff there are #6.022 xx 10^23# individual items of stuff, or #N_A# items of stuff, where #N_A# #=# #"Avogadro's Number", 6.022xx10^23#.

Explanation:

Here, your stuff is sulfuric acid. Thus, there are #2xxN_A# individual hydrogen atoms, #N_A# individual sulfur atoms, and #4xxN_A# individual oxygen atoms, in #N_A# sulfuric acid formula units. Here, I have used #N_A# as I would ANY other collective number: half-dozen; dozen; score; century. Of course, Avogadro's number is rather larger than the other numerical terms.

What is the mass of this #1# #mol# #"sulfuric acid"#?
