Answer :

Answer:

The correct answer is - 18.

Explanation:

The number of hydrogen atoms is indicated by the formula (NH4)2C7H10O2  that has two parts (NH4)2 and C7H10O2 then

Number of hydrogen atoms in (NH4)2 = 4*2= 8

number of H atoms in C7H10O2 = 10

then the total number of atoms = 10+8

= 18.

Thus, the correct answer is = 18 hydrogen atoms.
