8H8H

Explanation:

The only hydrogen in the compound above,

(NH_4)_2CO_3(NH4)2CO3

is in the (NH_4)_2(NH4)2 section. You can ignore the CO_3CO3.

(NH_4)_2(NH4)2 means there are 2 NH_4NH4 groups.

NH_4NH4 has a total of one nitrogen and four hydrogen atoms, which you tell from the subscript (small numbers). If there are no numbers, assume it is a 11.

Since there are two of these NH_4NH4 groups, and one has four hydrogen, then two must have 88.
