Question

How many atoms of each element are present in 1 mole of `H_2SO_4`?

Answer 1

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"`?
